Hi, all. This is my first time posting here. A friend suggested I join this community, because even though I don’t yet have a official diagnosis, I am certain BPD is what is causing so much pain and destruction in my life. 
Just recently, I completely ruined what could have been a really good and healthy relationship because, like I do, started getting insecure (for totally made up reasons I convinced myself were true) and lashing out. 
The worst part is I could feel how irrational I was being, but couldn’t control my reactions to my internal dialogue. 
Obviously, most “normal” people, don’t want to deal with that type of irrational behavior, so things ended rather abruptly when this ugly part of me surfaced. 
Anyway, I’m feeling really down about it. Feeling like I’ll never be able to find or have a long lasting and loving relationship. I don’t really see the point in life if you have no one to share it with, so this deeply depresses me. 
I am working on getting into a therapist, but in the meantime, what are ways you cope with living with an affliction like this?
