hahahaha!
I'll raise my hand on this one. I'm here and diagnosed with PTSD from childhood sexual abuse. My thought was just like yours when I first was diagnosed. "But I'm not a veteran." was my response. But the more research I did on Ptsd, I came to realize that I was a texbook case! Hard to come to that conclusion when I was in the denial stage.....
Anyway, I hope that you stick around and heal some. This place is a sanctuary to me. I hope the same for you.
