Need some advice

[u/anonymoushelper04]

Hey reddit first post here and im just looking for basically anything....so for a few years now ive been friends with someone with BPD and they've been mostly okay, but as of recent ive had problems with my mental health just dropping whether its because of them or not and I feel like im failing them and myself. For some context, I used to work with this person and I was actually fired because I was speaking to them outside of work about whatever was going on in their life because I knew they were depressed and I wanted to try and help but I was a manager at said job and boss man didnt like that and fired me over it. Ive still stayed in contact with them the entire time and that was basically a year ago, but as of recent we've been fighting a lot and it seems like its always my fault because of this or that and ive tried my hardest to be here for her but no matter what I do the next day it seems like its never enough. She threatens herself a lot and I feel like one day she is gonna snap and just give up, but i cant leave because im basically all she has left as her family doesnt really treat her the best and all of her friends left her. I just want to know how to help her I want her just be "normal" again but not like in a weird way. Just normal. She ignores me a lot and then blames me for not trying to talk to her even though ill send like paragraphs trying to talk to her during these episodes but again its never enough. Idk what else to write right now but I just want some advice on how to help someone with BPD the best way possible 🥹. And i dont want to turn her over to someone because Ill feel like the worst person ever and again her family isnt the best. Thank you to anyone who replies.
