Meh, I tried to reply about your list yesterday but deleted it coz ye olde inner critic thought I was being too... something. It felt wrong.
The important part of my response was your list is what I would describe as symptoms you experience because of your lived life so far - and trauma, abuse, neglect, insecure attachment.... WHATEVER. You could explain most of that list with almost ANY DSM "diagnosis". But that doesn't mean you can't start working to minimize how you experience the things in the list, in the absence of pinpointing a diagnosis.
Maybe it would help to rank the symptoms on the list for continuity - always, sometimes, rarely - and then intensity. Maybe it would let you decide to shorten the list to 2 or 3 things to focus on changing or understanding in a deeper way? Maybe assign a tentative time limit - 2 weeks, a month - always remembering that if your exploration and work shows results you can always devote more time to it. Also - we tend to work on the same things our whole lives - to lesser/greater degree. Just like I can't really change my white hair - different hair cuts are helpful at projecting a younger, stronger image. And I feel more confident.
I know you're creative and very smart. I'm sorry you're also lonely. Maybe THAT'S because you feel isolated from your inner self? Instead of needing other people/community. I dunno - but you can figure that out.
I'm just spitballing some ideas that might/might not inspire you into a direction. You sound a lot more open and clearer these days. So, maybe you're getting close to an actual breakthrough - hatching out into a spring chicken??? LOL. Rebirth.
