I've also experienced the same thing. My pdoc has called my mixed episodes a combo of bipolar&PTSD. With the PTSD you can feel happy, sad, angry, frustrated&numb all at the same time. Hope you're doing better. I used to take Risperdal&found that it was helpful to take it at night rather than during the day because of the tiredness issue. I seemed to sleep better&more regularly after that. Now I'm on Wellbutrin XL&Geodon&they're helping.
