Hey there, before I start I just want to make it clear that I have doubts on having BPD, but it's what my therapist theorizes I have and when I read the symptoms, it matches perfectly with me. I'm not diagnosed professionally by a psychiatrist or psychologist, just a really passionate therapist. I'm in a relationship with someone whom I love very much. I have a family that tries their best to support me and a group of friends who are happy to have me by their side. Also forgive my english, it's not my first language.

Even though the support I have, but 'with' this disorder, I feel like I'm a walking disease, or a bomb.

Everytime I interact with people there's a huge chance for me to hurt them. And I despise that. Everytime I f#ck up or just hurt someone unintentionally, my world falls apart. I get anxious, stressed, worried that I'll be alone, all of that pazazz. 
I've been going out and into phases of self harm, suicidal thoughts and tendencies, depression, anger, and so on. I'm really getting tired of this stress inducing roller coaster ride.

So I decided to self isolate myself until I get a grip onto what the hell is going on inside of me. I'm having trouble with it because of my fears but I'm trying to commit. I've locked myself away from most of my friends, family included. But I've been getting doubts if it's the right thing to do. Any suggestions?

TL;DR: I feel like I hurt too many people and now I'm Self-Isolating myself from everyone, but I'm doubting if it's the right thing to do. Help?
