Yup, knoe exactly how it feels.

I can totally relate to that. I don't filter out what I can or cannot say during on spot conversations. And I've been in trouble for that many times. And then I also get this kind of paranoia and tell myself I'll stop, but it just adds to the stress and nothing works out. For example, recently I left my job and I live in a small town and was on a job interview in a type of shop just like the previous one. And the boss was very likely to know my previous boss which I had a good contact with, still - she was asking me a lot to get to know as much information as possible of what I was thinking of the last employer and his business - and I started saying everything straight off, including the fact we were not printing all the paper bills we should and blabbering - when I got confused about how we were counting our monthly wages - that oh, sometimes my co worker (which I liked also) would not count enough, etc etc. And then I went out, thought about it and was like Sweet Jesus, you stupid...
I stopped talking to my co worker, met my boss while I was shopping, he was behind me, but I was too paranoid to react and talk to him and was thinking a lot about that the possibility of them knowing each other was pretty high because my boss was even talking once about talking to some other lady who had a shop like this and just grew completely embarassed...
I am also very critical and been even verbally and physically attacked for that during a party.
I'm not bipolar.
