If someone has been through one or more traumatic experiences in their life, such as sexual assault(s), physical assault(s), child abuse, extreme bullying, etc., many will call the person a trauma victim.
However, I've had psychotherapists tell me that if you've been through trauma in your past, you aren't a trauma victim. Instead, you are a trauma survivor. The thing is, the trauma didn't literally kill you because you are still here, which makes you a survivor, not a victim.
I think that's a good way to look at it. I'd rather consider myself a trauma survivor than think of myself as a trauma victim. The reason is because it makes me think and feel that I have more control over my life and more control over what happened to me. If I went through the rest of my life thinking of myself as a victim, I wouldn't be doing myself any favors.
