There is a stubborn belief, especially in pull-yourself-up cultures, that if something did not happen directly to you, it should not affect you. People want to assume trauma stops with the person who first lived it. That is not how trauma works. Not biologically. Not emotionally. Not across generations. Trauma does not live only in memory. It embeds in family systems and daily practices. If nobody interrupts the system, it keeps replicating quietly, reflexively, and sometimes violently.
What actually gets passed down
Trauma can alter the expression of genes. That is epigenetics. Stress, famine, displacement, and chronic fear can leave biochemical markers on DNA packaging that change gene function without changing the genetic code. What parents and grandparents endured not only shapes family habits. It can shape how a nervous system responds to threat, attachment, and safety many decades later. In a landmark study of Holocaust families, researchers documented shifts in methylation of FKBP5, a regulator of the cortisol system, in survivors and in their children who did not live through the original events. Comparable patterns show up in other contexts as well, including families affected by war, genocide, severe discrimination, natural disasters, and refugee flight. The point is simple. When people say trauma runs in a family, it is not just a figure of speech.
Inherited trauma rarely looks like a story
What passes forward is not always a narrative or a flashback. It often looks like a survival strategy that does not match the current environment. A child grows up in a safe home, yet cannot sleep unless every curtain is closed and every door is checked. A teenager treats disagreement like a death sentence, even in a respectful household. An adult keeps pushing away secure partners because the body has learned that calm usually comes before danger. These are not quirks. They are trained reflexes. They stay invisible until someone starts asking the right questions.
You do not inherit a diagnosis. You inherit the coping
CPTSD is not handed down like eye color. Defense patterns are. Silence is. Emotional constriction is. When trauma is not processed, it leaks into parenting through control, through chaos, or through inconsistency that leaves a child sensing danger without language to name it. Children repeat what works, even if it only worked in the old house. They pass it on not because they are broken, but because they were trained by example.
When pain gets ritualized
Trauma does not always announce itself. Sometimes it hides inside rules that are treated as virtues. Do not talk about feelings. Stay productive no matter what. Outsiders cannot be trusted. Keep the family’s business inside the house. Loyalty above all. The same mechanism hides domestic violence that nobody names. It hides animal abuse that neighbors avoid reporting. It hides generational child abuse that gets rebranded as strict parenting. In some families, stints in jail become a rite of passage rather than a warning sign. From the inside, these patterns sound like culture or tradition. Trace them backward and you usually find war, forced moves, addiction, shame, betrayal, or plain neglect. When trauma is not processed, it gets ritualized. It is repackaged as rules, reinforced as identity, and handed down as survival even when the danger is long gone. Dysfunction is often inherited pain on autopilot.
Breaking a pattern requires recognition, not avoidance
Moving on without naming the pattern does not change the pattern. It extends it. Real change starts with accurate labels. Name what happened in the family line, even if it was not your direct experience. Notice the default settings that make no sense in your current life. Choose deliberate counter-moves. Rest when the old rule says grind. Set a boundary where the old rule says keep secrets. Speak where the old rule says stay quiet. This is demanding work because you are not only adjusting your mood. You are rerouting generations of survival programming. That is heavy labor, not a slogan. It is also where the leverage sits. You are not obligated to carry the pain forward because it was handed to you. The future of the pattern is not fixed.
Final thoughts
If you feel like you were born carrying grief that did not start with you, or fear that does not match your lived history, you are not defective. You may be the first one who chose to hold up the mirror. You get to decide what continues and what ends.

Dr. Mozelle Martin is a retired trauma therapist and former Clinical Director of a trauma center, with extensive experience in forensic psychology, criminology, and applied ethics. A survivor of childhood and young adulthood trauma, Dr. Martin has dedicated decades to understanding the psychological and ethical complexities of trauma, crime, and accountability. Her career began as a volunteer in a women’s domestic violence shelter as a hospital advocate, later becoming a Police Crisis Therapist working alongside law enforcement on the streets of Phoenix. She went on to earn an AS in Psychology, a BS in Forensic Psychology, an MA in Criminology, and a PhD in Applied Ethics, ultimately working extensively in forensic mental health—providing psychological assessments, crisis intervention, and rehabilitative support within prisons and jails. Dr. Martin is also pursuing advanced legal studies at ASU Law, focusing on internet/cyber-defamation and constitutional law to advocate for stronger protections against targeted professional attacks online. A published author and lifelong student of life, she continues to explore the intersections of forensic science, mental health, and ethical accountability in both historical and modern contexts.
