I've ended several good friendships over the years. Mostly due to paranoia and also due to a decreased tollerance for anything when dysphoric/manic. In my case, I'm never sure if I ended a great friendship or if paranoia got the better of me. It's very distressing and something I'm struggling with hard right now. I have no advise because I haven't gotten it figured out at all.

I'm sorry you are struggling with this also. (((Hugs)))
