Excuse me? Because you're not a mess you're not a "true victim"? You do realize you have come to believe this yourself, right? Look at your words again- "I didn't fit in. My trauma didn't affect me the way it did them".
Well guess what? I've been through the trauma of rape TWICE and I'm still not an emotional mess. In fact, I'm pretty normal. I can be around men no problem because I realize that the actions of a couple don't reflect the actions of men as a whole. I'm a mother of two, married and getting my degree. Would you call me less of a survivor (I really just despise the word victim and never use it for myself) just because I don't flinch every time a man talks to me and I don't spend days on end sobbing in bed and I'm able to have a normal, healthy relationship?
Never again let anyone tell you what you are or aren't. That's for you to decide. Maybe you can start a group yourself. There's no telling how many people who don't fit that twat's "victim mold" that she's asked to leave the support group. I am more leaning to that it's because you're male and that is extremely fucked up. This person is only helping those that SHE deems true victims and that is so damn wrong, it's scary. Everyone needs at least some support and if she's picking and choosing who is allowed support then she is not as good of a person as you seem to think. Were there other men in the group? There are actually people who believe that men cannot be victims of rape or sexual assault and that is wrong. There are many that need just as much support, if not more simply because they are not believed by much of society.
Someone needs to have a talk with that idiot and let her know that she doesn't get to decide who us "victim enough" to get support. Please tell someone on campus, if not for yourself, for the next person who needs support but doesn't fit that woman's idea of what a true victim is.
