I've been told by doctors that C-PTSD and EUPD can cause everything you're describing. Keep in mind these diagnoses are just concepts, not real things, but the trauma you've experienced and what's happening in your brain is very real. The depression, anxiety, and emotional distance from your environment sounds like PTSD. Nobody should diagnose you over a forum, especially not an unqualified person like me. Jburg is right, talk therapy and psychoeducation seem to be warranted here. If you're able to achieve a state of peace and equanimity then you'll be able to be calmer and more authentic. A lot of people are faking to some extent just to get by, especially with mental health. It can be socially problematic to admit you feel like shit and would rather be doing something else. I'm no trauma expert but we've gotta strike a balance between sheltering ourselves and making ourselves do things.
