I concur with the others, the best person to determine if you have PTSD is a professional....I was diagnosed with PTSD in 2002, and now by seeing a trauma therapist she has determined through seeing me a few times and getting to know my baseline...that I have Complex PTSD.

But self diagnosing can be really confusing. It's always best if you feel like you have something going on to try to see someone knowledgable who can determine what exactly that is that you have going on....
