I know exactly what you are talking about. I used to get like that all the time. But I think my meds took it away (or something did). It really sucks. One time, I got stuck baby sitting my nephew and he was crying (as babies do) and I couldn't do anything but sit there and watch him cry. I felt so helpless but hadn't the drive/motivation/energy to do anything. I was emotionally indifferent. I mean, he wasn't in any danger (I was holding him) but I just couldn't act and didn't really care that he was crying. I felt so horrible after the fact. It's gotten me so far behind in life because I would slip in and out of this zombie-robot state. I hope you can feel again soon. I wonder though: your signature says you're sza. Do you think this one of those "negative symptoms" of the sz aspect that I've heard about? (Of course that wouldn't explain my similar experiences, but maybe yours?)
