Welcome, Thisisnotforyou!
Let me welcome you here to bpdfamily and wish for you as much help and support as I have received. It's clear you have a lot in common with many of us here. This is a community where we help each other, so I'm sure if you keep posting and reading you will find it helpful.
Thank you for sharing what you have thus far:
How am I supposed to reconcile the fact that by cutting out my abusive friend I’ve also lost a friendship that wouldn’t have ended otherwise. I’m angry about the whole thing, and sad, and yes I’m in therapy but this is sticking with me for some reason.
It sounds like you have really had a tough time, and I'm sorry for that. One thing that can really help with allaying some confusion is understanding. And, it sounds like you are willing to understand BPD better, and that is pure genius, in my opinion. The more you know, well, the more you know! Luckily, you've found our website which can help you in that regard in spades. When you're ready, just start reading the site articles and do the Tools and Lessons located in the right panel of this page. The other thing that you'll find here is support for
yourself.
I think you're behaving rather above board with stepping back from continuing a friendship with your bestie's boyfriend, as that would, no doubt, cause never-ending drama for everyone. It must really sting to lose that friendship though. I am sorry. Is it possible that this may not always be the case?
I believe you will be greatly comforted by the support here and the fact that we really understand what you are going through. We've all been there to varying degrees. Take care of yourself. We will look out for future posts from you.
Keep writing, keep processing, keep learning!
