Yeah, it's a thing I used to do, too. My T finally retrained me into "This is not going to be a disaster". Sometimes, I have to repeat it like a mantra. After a few years, I even began to believe it, and now I trust that everything that goes wrong isn't going to be a catastrophe. I know it's a borderline trait, and I'm wondering if it's one shared with bipolars.

Maybe the rubberband snap might help. Bad thought = snap = tell yourself this is not going to be a disaster.
