That sounds like part of the syndrome. One of the things is change in mood from really liking someone to hating them. This dichotomy is precisely part of what you feel. You are not alone, it took me a long time to understand that the problem is not me, but the disease I suffer from. My psychological treatment and the pills really helped me deal with these feelings and today I am more balanced.

Journaling has helped me a lot. You can see exactly what you're thinking with your own eyes and see what's logical and what's not, and it triggers the brain to think in a more balanced manner. My anxious attachment or FP issues have subsided a lot because I was able to see what was caused by my disorder compared to what was happening. It also kept me busy enough to give my person space without worrying about them, needing them, or resenting them for lack of attention. Now I can go without hearing from them without it being a trigger more often.

oh my god samee

It’s part of bpd unfortunately. I felt this way for a while too. But for me it was more of a once I have a fp, I need them in order to survive lolll. After lots of chaos and pain I’ve just stopped developing an fp tbh. Not feeling like I need someone for my well-being has helped me so much. I don’t isolate myself and I’m not promoting not developing friendships but devoting my time to things like work has helped me not develop unhealthy attachments to people. Sorry that was confusing and idk if it helped but that’s my experience.
