If someone does anything minor I assume the worst things and i get hurt and angry and imagine how life without their friendship would be like, which hurts me and i say hurtful things and i don’t sugarcoat my feelings or what i think, it can come out aggressive.  

I don’t know how to set a healthy boundary, it’s either 24/7 communication and care or they hate me and don’t care about me. And it’s making my friend upset which is understandable because im adjusting to the fact that she has new friends in the new city she’s in. abd she says it feels suffocating .And i may see a picture of her with them being together and immediately think “she’s done with me”, “she was using me because she had no one else but now she doesn’t need me”, “she doesn’t care about me and she’s too busy with them to even text me”   

i also used to ask my ex every single day if they were thinking of breaking up with me, just to make sure they’re not and i’d ask if we’re doing okay and make them promise that we were.

my anger manifests in a very hurtful way to others and it’s like explosive

I don’t even know if these are bpd signs or something just in me because the internet is not clear at all and i’m really sorry if it isn’t bpd , i don’t want to self diagnose i just want advice from anyone that might relate.
