How Trauma Becomes PTSD

How Trauma Becomes PTSD

Trauma is not just about what happened—it is about how your mind and body respond when an experience feels overwhelming, threatening, or impossible to process.

After a traumatic event, many people find themselves stuck in survival mode. They may avoid reminders of what happened, feel constantly on edge, struggle with intrusive memories, experience emotional numbness, or notice changes in how they see themselves and the world around them. Over time, these reactions can begin to affect relationships, work, motivation, enjoyment, and overall wellbeing.

This handout introduces The Psych Collective's PTSD model, which explains how trauma can develop into ongoing post-traumatic stress symptoms. It explores the role of vulnerability, avoidance, hyperarousal, emotional fatigue, and the long-term impacts trauma can have on thoughts, emotions, behaviours, and identity.
