How do you cope with having BPD and being in love with someone? 
I feel completely obsessed and like my entire world revolves around the person I’m in love with and if we argue or things aren’t 100% perfect I feel like my world is crumbling.

I’m constantly obsessing over them leaving me or cheating on me. Even though they’ve given me no reason to believe that at all. I feel like an absolute mess. 

I don’t want my whole existence to hinge on how I feel about someone because if it ends then I will just crumble but the feelings are so overwhelming. I can’t explain it. 

Does anyone else struggle with this?
