Breakthroughs symptoms and conditions

I began taking paxil 30mg for anxiety attacks with xanax to help with the breakthroughs. Then it was upped to 40mg but that made me very aggitated, so it was reduced to 30mg again. I've been on Paxil since 1996. Recently, my dr. increased it to paxil cr...with this I havee moments of dizziness and dis-connected feeling even if I'm just sitting still. I worry about the side effects and wonder if I am doomed to stay on this forever. I have had to add valium and geodon for auditory voices,and now a stomach pill to help the stomach pain all these drugs cause. At first, I thought this drug was a life-saver, but now I'm not so sure,especially at 40 pounds heavier.
