Why Your Depression Keeps Coming Back (And How to Stop It)

Marie, 38, walks through my office door in Nantes with an expression I recognize immediately: the mixture of hope and resignation of someone who has already been through several depressive episodes. "Doctor Garrec, I'm afraid it's starting again," she confides from the very first moments. "The signs are there... this fatigue settling in, these dark thoughts coming back. I feel like I'm trapped in a cycle I can't break."

This situation is one I hear regularly in my clinical practice. Recurrent dépression affects approximately 50% of people who have experienced a first major depressive episode, and this risk increases with each new episode. But here is the good news: Cognitive-Behavioral Therapy (CBT) offers concrete, scientifically validated tools to break this cycle.

Through fifteen years of therapeutic support, I have observed how certain strategies truly help prevent relapses and regain control over one's mental health. This article reveals these approaches, enriched with clinical examples and practical exercises you can implement starting today.

Understanding the mechanisms of recurrent dépression

The vicious cycle of relapse

Recurrent dépression takes hold through a well-identified mechanism in CBT. When a mildly depressive mood appears, it automatically reactivates old negative thought patterns. These thoughts generate painful emotions, which in turn reinforce pessimistic thinking, creating a downward spiral.

In my practice in Nantes, I frequently observe this typical sequence:

• Initial trigger: work stress, relational conflict, change of season


• Automatic thoughts: "I'll never get through this," "It's stronger than me"


• Émotions: sadness, despair, anxiety


• Behaviors: withdrawal, procrastination, avoidance


• Consequences: confirmation of negative thoughts, worsening of symptoms

Vulnerability factors

Certain elements increase the risk of depressive relapse:

• Cognitive factors: tendency to ruminate, perfectionism, low self-esteem
• Behavioral factors: social isolation, unbalanced lifestyle, avoidance of difficulties
• Environmental factors: chronic stress, toxic relationships, stressful life events
• Biological factors: neurotransmitter imbalances, genetic predispositions

Relapse prevention is not about avoiding all triggers — which is impossible — but about developing skills to respond differently.

Identifying early warning signs

Creating a personalized prevention plan

With my patients, we develop together what I call a "relapse radar." Thomas, 45, an executive from Nantes who has been through three depressive episodes, learned to recognize his specific warning signals:

His identified early signs:

• Difficulty falling asleep for more than two consecutive nights
• Tendency to postpone enjoyable activities
• Recurring thoughts about his past "failures"
• Decreased contact with loved ones

His immediate action plan:

• Resume progressive muscle relaxation exercises
• Schedule a pleasurable activity within 48 hours
• Contact a close friend to maintain social connection
• Review his list of alternative thoughts prepared in therapy

Structured self-observation

I recommend my patients keep a simple but regular "emotional logbook." Here is the method I use in my practice:

Daily evaluation (5 minutes in the evening):

• Overall mood out of 10
• Energy level out of 10
• Sleep quality out of 10
• One positive thought from the day
• One self-care behavior performed

This practice allows you to detect fluctuations before they become firmly established. Taking our free psychological tests can complement this self-observation with standardized assessments.

Developing protective cognitive strategies

Preventive cognitive restructuring

One of CBT's most powerful tools involves preparing alternative responses to typical depressogenic thoughts. In session, we work on what I call the "cognitive toolbox."

Restructuring example with Sophie, 29: Automatic thought: "I'll never be able to maintain a stable relationship" Challenge questions:

• Is this thought based on facts or emotions?
• What would I say to a friend who had this thought?
• Is there evidence to the contrary in my experience?

Constructed alternative thought: "I have relational difficulties to work on, but I also have capacities for love and connection that my loved ones recognize"

The 5 whys technique

When a negative thought arises, this technique allows you to explore its roots:

Why do I think this situation is catastrophic?

Why is this fear so present in me?

Why do I need to control this situation?

Why is this fear of failure so strong?

Why does my self-esteem depend on this success?

This exploration often reveals deep schemas that can then be questioned and loosened.

Mindfulness training

Third-wave CBT approaches, such as Mindfulness-Based Cognitive Therapy (MBCT), show remarkable effectiveness in relapse prevention. I regularly suggest this exercise:

Cloud thoughts meditation (10 minutes):

• Settle comfortably, eyes closed
• Observe your thoughts without judging them, like clouds passing by
• When a depressive thought appears, mentally note "thought" without grasping it
• Return to the compassionate observation of your mental flow

This practice develops what we call "decentering": the ability to observe your thoughts rather than identifying with them.

Strengthening protective behaviors

Preventive behavioral activation

Contrary to popular belief, you should not wait to feel motivated before acting. Behavioral activation teaches us that action often precedes motivation. In my practice in Nantes, I help my patients build a structured "anti-relapse schedule."

Essential behavioral pillars: 1. Regular pleasurable activities

• Schedule at least 3 pleasurable activities per week
• Vary between social, creative, and physical activities
• Maintain them even when mood fluctuates

2. Lifestyle routine

• Regular sleep schedule (consistent bedtime/wake time)
• Moderate but consistent physical activity (30 min, 3 times/week)
• Balanced diet with meals at regular times

3. Social connections

• Minimum weekly contact with 2-3 close people
• Participation in a group activity (sport, hobby, volunteering)
• Avoid isolation even on "bad days"

The behavioral contract technique

With Julien, 35, an IT professional from Nantes, we established a precise contract:

Minimum weekly commitment:

• 2 cycling outings (Tuesday and Saturday morning)
• 1 social activity (after-work drinks or evening with friends)
• 1 creative moment (guitar or drawing, minimum 30 min)
• Family call on Sunday

Reinforcement system:

• Week completed = chosen "bonus" activity
• 3 consecutive weeks = more ambitious goal (discovery weekend)

This behavioral approach creates a safety net that maintains a protective activity level even during difficult periods.

Building a solid support network

The importance of structured social support

Research clearly shows that isolation is a major risk factor for depressive relapse. In my practice, I work with my patients on the methodical construction of a multi-tiered support network.

Typical support circle: Level 1 - Intimate support (1-2 people):

• Partner, close family member, very close friend
• People informed about depressive history
• Reachable in case of crisis

Level 2 - Regular support (3-5 people):

• Close friends, caring colleagues
• Weekly social interactions
• Regular shared activities

Level 3 - Community support:

• Activity groups, associations, sports clubs
• Colleagues, neighbors
• Sense of social belonging

Preventive communication with loved ones

I encourage my patients to prepare their loved ones to help effectively. Here is the guide I suggest:

Information to share with your inner circle:

• "When I go through difficult phases, I tend to..."
• "What really helps me in those moments is..."
• "The signs that should alert you are..."
• "Here is how you can concretely help me..."

Celine, 42, explained to her husband: "When you see me canceling several outings in a row, don't hesitate to gently but firmly suggest we go for a walk together. And remind me that I've been through this before and that it can pass."

This approach avoids both overprotection and neglecting warning signs. In couple relationships, these issues can be particularly complex — don't hesitate to analyze your couple conversations to better understand your relational dynamics.

Integrating complementary thérapies

EMDR for treating underlying trauma

In my practice, I often find that recurrent dépression is rooted in unresolved traumatic experiences. EMDR (Eye Movement Desensitization and Reprocessing) can significantly reduce relapse risk by treating these traumatic foundations.

Case of Marc, 50, entrepreneur from Nantes: His depressive episodes were systematically triggered by professional difficulties, reactivating a school humiliation trauma at age 12. After 8 EMDR sessions targeting this memory, his reactions to professional stress were considerably eased.

Acceptance and Commitment Therapy (ACT)

ACT remarkably complements classical CBT by developing psychological flexibility. Its 6 therapeutic processes offer powerful tools:

1. Acceptance: Welcoming difficult emotions without struggle 2. Cognitive defusion: Distancing from problematic thoughts 3. Being present: Developing attention to the present moment 4. Self-as-context: Cultivating a flexible perspective on the self 5. Values: Clarifying what gives meaning to your life 6. Committed action: Acting in alignment with your values ACT exercise - Values clarification: List 5 important areas of your life (family, work, health, creativity, spirituality...). For each, ask yourself:

• What truly matters to me in this area?
• How can I honor this value this week?
• What small action can I take today?

This approach creates a powerful intrinsic motivation that withstands mood fluctuations.

Effective prevention of depressive relapses does not rely on a single method, but on the creative integration of several complementary approaches tailored to each individual.

Creating a long-term personalized prevention plan

Assessing individual risk factors

Each person presents a unique vulnerability profile. In my Nantes practice, I use a comprehensive assessment grid that allows precise customization of preventive strategies.

Factors to assess: Personal history:

• Number and intensity of previous episodes
• Identified triggers (seasons, stress, relationships)
• Strategies that have worked in the past
• Current or past medication treatments

Current context:

• Level of professional and personal stress
• Quality of important relationships
• Physical health status
• Available resources (time, finances, support)
