zyprexa vs. seroquel

REAlly sick today. I feel like surreal. I hear the loud and clear voices. They dont really tell me to do anything anymore they just try to mess up my thoughts. I see an intense hatred they have for me believe me man these things are ugly. Im thinking about getting  back on my previous medications. The thing is on the stuff im on right now that i cant focus. Not so much on tasks. Im not worried about that as much, but i cant focus on me, and these voices have such influence over my thought pattersns right now that i dont even recognize my own thoughts sometimes. I know if i get back on zyprexa my cognitive abilities will be dulled, really  dulled. I run the risk of making an embarrising jackass out of myself on it in stressfull situations. At least with these meds im on now the seroquel, I feel like i can hold my own a little bit as far as healthy functioning of the brain, but that is about the only con of being on zyprexa. I know who i am on zyprexa and it is crystal clear. I enjoy self esteem and i was really a lot of the time consistently happy on it. So, im torn between a 30 pt lower iq or feeling like myself all the time crystal clear, and plus i can lose weight on zyprexa easier. Im just worried about my dignity when it comes to being on the zyprexa.
