Seroquel and stay calm

I am a 26 year old female. I have been on seroquel for about 3 months. Since taking seroquel I have gained about 20 lbs and seem to keep gaining. My breasts have gone up a full cup size. I also feel nothing, by this I mean I feel no emotion. I don't feel happy, sad, glad, or mad-- I feel like I am just here. I almost feel like I am lost- I can't stay focused, I can't complete a thought, it's almost like I'm in a constant state of daydreaming about nothing. I take a small dose of seroquel 3 times a day to stay calm and a larger dose at nite to sleep. It works as far as that goes but the weight gain and the loss of emotion concern me.
