Sick... strange to me... help?

Ok so I got on some new meds about a week ago for anger and it's supposed to clam me down (anger issues) anyways and yesterday afternoon my boyfriend had waited for my parents to pick me up after school before he walked home. He said I had passed out 3 times. This morning I didn't wake up in a very good mood but I ate and I felt a tad bit happier. But then I got to school and I felt horrible and still do. I don't feel very nauseous just dizzy and my boyfriend said that I kept passing out this morning and he made me lie down and I wasn't tired or anything but when I tried to get up my ribs hurt! I've had x-rays before on my ribs and they said noting was wrong but something is I know it is. For god's sale I go to sleep by like 7pm and sometimes even earlier! I'm not so sure whats going on. can anyone help?
