Jean,
I can relate to a lot of what you wrote. I've had some of my worst work experiences since I've been sober. Some of it has to do with external circumstances, but I think the way I react (and I, too, worry about the quality of my work and overcompensate by working harder and judge myself harshly when I perceive that I'm not being properly appreciated) has to do with ME. Sometimes I almost literally shut down and can't concentrate on what I'm doing.
I'm coming to the same conclusion you are, which is that I need to start doing serious step work.
Meantime, no, I don't think either one of us is going literally crazy, but we are a little screwed up. I also think, in my case, I have a touch of PAWS that hits from time to time, which affects my cognitive abilities. I will sometimes have "brain fog" or blank spots in my thinking. Sometimes that will cause me to panic a bit, which, of course, doesn't help. It does pass, eventually.
Just wanted to let you know I understand how you feel.
