Marion-Y, how long since the last risperdal shot?
I do understand how awful it feels. I was on risperidone, many years ago now. I agree it is true, true hell. (The only worser hell I have experienced was largactil/chlorpromazine).
My sincere advice.. Engage your mind rather than observing your mind so intensely, for now, if you see what I mean. Maybe keep a journal, and jot down a few notes each day to track your progress. But otherwise, look outward for now.. Go for walks, watch documentaries.. start with small things.. For example, I did a lot of logic puzzles and word games when I was finally coming off it, it was the best I could do and even that was hard! But I kept at it. Skip forward some time, I eventually returned to a rather technical job and did many many other things that I thought were lost to me forever.
I don't believe ECT is the solution for you. I believe you are having a difficult patch and need to allow yourself time to heal. Please hang in there.
