Hello!
I so sorry to hear that you are experienced this. Interpersonal relationships can be really tricky navigating (and extra tricky with the added BPD). I too (as someone with BPD) have found relationships quite tricky and understanding the societal expectations and nuances. One thing I have found rather helpful is finding community with likeminded people whether this be people with common hobbies (e.g. dungeons and dragons) or have a understanding on mental health so that you both may be able to find commonality and understanding in your lived experiences.
I hope that you are able to find relationships and please know you are well worth being here!
