Having known so many people with this and even experiencing it myself, it's a difficult journey to find a way to deal with trauma in a healthy way. There are plenty of unhealthy coping mechanisms such as self-harm, alcoholism, drugs, etc.., dealing with your day to day life can be hard and some people might not even know they have it because it can be something so huge it's obvious; yes this caused trauma; or something that seems so irrelevant that you don't want to believe you're reacting this way. When someone is in that rut it's almost impossible to come out of it without real help, some people are stuck in the situation if their trauma is a relative like someone they're stuck with whether it be a child and their parents, or college roommate, etc. The journey is long and only the victim can really move from it, but for anyone struggling, I hope this video might help a little.
