I have obssessive thoughts too....and they started way early in my illness.......when I was thirteen, I was obssessed by the fact that I was taller than everyone else....then I was obssessed with astrology, then various guys, then mind reading, now I get obssessed with how people give me their order while I'm waitressing (be nice to your waitresses, please people........) it's always something!! You write your thoughts take up a lot of time during the day, is it to the point that other things that need to be done don't get done? When thoughts interfere with the rest of life, that's when one should be concerned...neglect in care and changes about weight, yes they are changes that can be talked about, talking helps from feeling one has secrets....write us more?
