I'm the OP. Thanks for all the responses everyone, really touched me, for a while. I guess I'm just hardwired to stop myself from wanting good things and sabotage the chance of every good thing that comes my way. I shut out people on my own, consciously or subconsciously.
I've tried pure MDMA once, low dose though, and got into an arguement with a close friend instead of bonding with anyone. As for therapy, I'd love that. But the country/society i'm in isn't concerned with mental illnesses. I would have started therapy years ago if I could, I looked everywhere. The few I did find were way too expensive to see regularly. So I just made up my mind that I'd have to learn to live with borderline and depersonlisation and all the related stuff. I have learned to live with it, just that now it's a dead end existence, as good as being dead without any of the passion and motivation and energy I had before, even if it was negatively focused.
