Still on meds

Well I'm still taking tegratol, 3pills in the morning, 3pills in the afternoon and 4pills at night.  I don't know if it's the medication but everyday off and on I think that I'm going to die of some kind of terminal sickness.  For the past week I've been getting dizzy so of course I'm thinking it's something serious and I'm going to die.  It's really awfule to have theses thoughts all day everyday.  It's scary and depressing. I can't stand it anymore!!
