I feel for you, Daisy. I have to sit in on those ambush meetings for myself all the time, and I hate them. The next one will be the last one. I have to remain "stable." I feel like asking a bipolar person to remain stable is like asking a blind man what color shirt you're wearing. Maybe that's just me...

Anyway, I think it isn't weird to feel relief. Knowing is always better than not knowing. If they let you go, get on unemployment if you can. Make sure you have a documented copy of everything, plus documentation from your doctor about your bipolar.
