Also from what I read in your story, neither of your parents nor other adults at school were emotionally available to you. Sounds like strong "emotional neglect" which Pete Walker in Complex PTSD the book says is the key creator of CPTSD, emotional neglect with no "good enough" parent...
I'm not a diagnositican but for waht its worth I've come to realize that I've always thought "I never had it THAT BAD" and yet I'm becoming more and more certain that CPTSD fits me - but the key was...I had no EMOTIONAL ADULT in my house. Mom and dad were present and gave me material needs...they did the best they could but...didn't leave me with that much resources emotoinally -- I lucked out in terms of still somehow being smart (IMO) but emotional intelligence was zero, and is just improving now at in the past few years, I'm early 30s now and have spend some time reading and in therapy. But 5 yearas of therapy stuff before tying everything to the CPTSD (ratehr than "just depressed" etc)
