When trauma has shattered your heart repeatedly, the world becomes a dangerous place where everyone feels like a potential threat. Your nervous system learns to protect you by shutting down your ability to trust, creating an invisible barrier between you and the connections you desperately crave.
The science behind why trauma breaks our ability to trust is both heartbreaking and validating. Research shows that trauma can shatter an individual's trust in themselves, others, and the world around them, causing betrayals and abuse to erode belief in the reliability and safety of people. When someone you should have been able to count on fails you in moments of deep need, after experiencing trauma, it becomes hard to trust the intentions and actions of others because someone has likely shown you that they are not safe to be trusted even if they were in a position to be trusted.
Your Nervous System Creates a Prison of Self Protection
Your body remembers what your mind tries to forget. Those stuck in sympathetic states may carry a story of fear, distrust, dysregulation, and anxiety, while trauma can cause neuroception to become distorted or biased toward detecting danger. According to polyvagal theory developed by Dr. Stephen Porges, when neuroception is biased toward threat, access to the ventral vagal complex is compromised, constraining the capacity for calm, connection, and self-regulation.
This biological reality means your nervous system is constantly scanning for danger, even in safe situations. In environments that are considered safe, a chronic fight-or-flight state is maladaptive and may lead to significant hypervigilant psychosocial distress. PTSD symptoms emerge when the nervous system operates from a maladaptive state and is stuck in fight/flight/freeze/fawn state, including hypervigilance, inability to participate in daily life, long-term fatigue, and feeling numb or shut down.
Your trauma responses happen faster than conscious thought. Trauma responses occur rapidly and unconsciously, with the single greatest tool for counselors being to slow things down and help each person begin to understand the automatic process that occurs for them, including the origin of the trauma, the individual's triggers, and the fight-or-flight response.
Attachment Injuries Leave Lasting Wounds on Your Heart
When the people closest to you fail to show up during your darkest moments, it creates what researchers call attachment injuries. An attachment injury occurs when one partner violates the expectation that the other will offer comfort and caring in times of danger or distress. When expected emotional support flounders, leaving one alone to process weighty emotions during key moments, the wound of abandonment cuts deep, leaving lasting damage. These emotional disturbances puncture our soul, spark incessant ruminations, and disrupt sleep. Once gouged and bleeding, hopeful dreams of security are shattered against the bare walls of aloneness.
The research on childhood maltreatment reveals devastating consequences for your ability to trust. Increased distrust and perceived interpersonal threat following trauma likely apply to individuals with childhood maltreatment, following a dose-response relationship. Evidence on increased distrust and perceived threat following childhood maltreatment could substantially inform treatment approaches, especially when patients are in treatment for conditions other than a trauma-related diagnosis.
Your Trust Issues Aren't Character Flaws
What you call "trust issues" are actually brilliant survival adaptations your nervous system developed to keep you alive. Often not recognized after trauma is that survivors lose trust in themselves, blaming themselves for some part of the trauma. This self-blame, while illogical, is still an expected result of trauma and must be addressed in trauma treatment. Your hypervigilance, your need for control, your difficulty being vulnerable aren't personal weaknesses. They're evidence that your nervous system worked exactly as designed to protect you from further harm.
The Childhood Blueprint That Shapes Adult Relationships
Over two-thirds of children report experiencing at least one traumatic event by age 16, with at least 1 in 7 children experiencing abuse or neglect annually in the U.S. When trauma happens during childhood, it creates a template for how you expect relationships to function. An overarching theme of unresolved childhood trauma can manifest in adult relationships as traumatic bonding and a compulsion to unconsciously repeat unresolved core wounds. Many traumatized people expose themselves, seemingly compulsively, to situations reminiscent of the original trauma.
The impact on your developing brain is profound. Studies found strong associations between childhood maltreatment and both decreased gray-matter volume in areas of the brain and increased response in the amygdala upon seeing pictures of threatening facial expressions. Sexual abuse in childhood has extensive lasting negative effects: these individuals develop a generalized fear response as a result of their inability to control or predict abuse, leaving them unable to emotionally engage in interpersonal relationships, feeling worthless and perceiving others as disapproving of them.
Breaking Free From the Prison of Mistrust
Healing your ability to trust doesn't mean becoming naive or ignoring red flags. It means giving your nervous system new information about safety. The polyvagal perspective argues that we should think of trauma in terms of retuning the nervous system. To heal ourselves, we should give the nervous system the cues of safety so that it re-tunes itself to being more homeostatic.
Recovery begins with small steps and safe relationships. With learning to trust yourself and others, take it slow. Trust yourself to follow through on your promise that you will do a load of laundry today. Over time, as these smaller promises are fulfilled and trust is proven, then larger promises can be made. While one heals from attachment trauma, they don't have to work on romantic relationships right away. They can start with a friendship, or a relationship with a therapist. Monroe advises asking yourself which relationship gives you strength and security. Then, you can look at what traits make that happen, so you can better understand how a healthy relationship can function.
The path forward involves both professional support and community. Recovering from trauma and rebuilding trust, safety, and control is a challenging but essential process. Therapies, support networks, and self-care play a significant role in this journey. Trauma-focused therapies, such as cognitive-behavioral therapy (CBT) and eye movement desensitization and reprocessing (EMDR), can help individuals process traumatic memories, develop coping strategies, and rebuild a sense of safety and control.
Your Nervous System Can Learn Safety Again
"The only way out of these attachment injuries is to confront them and heal them together." - Dr. Susan Johnson, clinical psychologist
Beyond the insightful research on this painful topic is the reassuring message that attachment injuries can heal. We can love and be loved again. Sometimes, we can achieve this within the same relationships; other times in the supportive arms of someone else.
Your journey toward trusting again isn't about returning to who you were before trauma. It's about becoming someone new who can hold both wisdom and openness, boundaries and connection. When survivors heal and reside in the ventral vagal state, they are able to let go of these stories and become more connected and attuned with others.
The Freedom Triggers Assessment can help you identify the specific triggers that activate your nervous system's protective responses, giving you a roadmap for healing. Understanding your unique trauma patterns is the first step toward reclaiming your ability to trust, connect, and love without the constant fear of betrayal.
Remember that healing isn't linear, and setbacks don't mean failure. Every small step toward safety, every moment of genuine connection, every choice to remain open despite your fears is rewiring your nervous system toward hope. You deserve relationships built on genuine safety, mutual respect, and authentic love.
