you're not butting in

. obviously, no one here can offer a diagnosis over the internet. it is not a requirement of c-ptsd that you have had multiple traumas, it is just more likely that someone with multiple traumas will develop c-ptsd than someone with a single event. but that is kind of like saying that it is more likely that someone over 50 will get breast cancer - it still happens to younger women, too!
if you think this is a diagnosis that could explain your symptoms, then i'd encourage you to bring it up with your T. as for myself, i had never heard about c-ptsd when i started treatment, and i related to a lot (but not all) of the criteria for borderline personality disorder, so bringing that up with my pdoc was what led me to be diagnosed with this instead.
i am sorry that you are going through everything you described. clearly, the important thing is that you receive treatment for all of those aspects, regardless of what diagnosis you officially receive.
being given the diagnosis has proven useful and informative for me. if i hadn't known, for example, that seeing yourself as a "bad" person was part of the clinical profile, i doubt i would have ever brought up that core self-concept with my pdoc - i would have been too scared that it was true, and i didn't want the confirmation. but knowing that it is part of the disorder helped me separate that from myself, a little bit. now on good days i don't think of myself that way.
