I hope you're feeling better soon. I'm on 300 mg seroquel at night, and the few times I have missed a dose I immediately started to feel anxious and paranoid, so I imagine you've got that times ten at the moment. I hear from others that though withdrawal is difficult it can be achieved. When I was on prozac, years ago (when they thought it was unipolar depression) I found withdrawal very difficult. But I did eventually get over it. Your body will adjust.
