I know I felt this way on risperidone---I was just ready to quit it with so many side effects including rapid weight gain but they were able to switch me to abilify and my weight gain has been bearable. The low weight gain APs are abilify, geodon and latuda have you tried them all? The next alternative is adding metformin to your existing regimen. Both these are options that don't involve going off the meds and won't get you into trouble with your mom or end with you being on AOT.
