Deathly afraid of being abandoned

I think im aware where this fear comes from as i’ve always had trouble maintaining relationships for some reason. It is never my fault but they always end negatively with the other party blaming me. I’m deathly afraid of abandonment as i latch on to people so easily and never want to let go or change. When i see them talk with other people more than me i get incredibly angry and scared. Idk what to do because anytime i get a very close friendship, i can’t stop worrying they will drift away, but i also have no clue how to stop them from drifting or if its even worth it.

I feel like im always the 2nd or 3rd choice but i can’t stand it.

Does anyone else deal with this?
