Well... my circumstances are such that I would not be in a situation where I would need to identify myself in relation to trauma.
But, were I to be, I think I would probably just try to describe what occurred rather than to apply a term to it.
I couldn't describe myself as being a victim, although that perhaps is what I was. I just dislike the term. And I don't feel much like a survivor because I still struggle with it even after all of these years. Fighter I don't think works either. I'm not a "fighter" in any sense of the word.
If I had to use some term to describe what happened to me I'd probably say I was a target; because that's what it felt like.
I doubt, though, that is quite what you had in mind when you posted this. Hopefully there will be other members who will have better suggestions.
