I'm sorry you are struggling with that. It sounds freightening. I have not passed out from my symptoms, but have had really nasty reactions to innocuous things... and the flashbacks really, really suck. (gntle hugs) if you want them...

fyi, you can have ptsd diagnosed by a clinician in the US, but they have to have diagnostic training. It doesn't have to be an MD... generally, diagnoses are really only useful for insurance purposes, and communicating a set of noted symptoms... *most* therapists and counselors are not qualified to make an official diagnosis, but licensed psychologists are, as are most PhD or PsyD level professionals...
