I too feel that "I'm about to die" feeling......It comes on in a swirl of panic and jacks me up so bad that I have to immediately take a Klonnie and a half a xannie. As the meds start to work the feeling subsides but when it hits me I'm positive that I'm about to die. The thing that works the best for me is to take my medicine faithfully and on schedule. I think my problem is that I often think I don't need the medicine, or more accurately, I don't WANT to need the medicine so I delude myself into thinking I'm OK without it. Then I get panicky and the voices tell me I'm about to die. When I get like that I cant leave the house mostly have to stay in bed until I begin to feel safer again. It sucks.
