Any suggestions for getting back on track after panic attacks?

I do that too, and I am thin as well. Eat a small amount of your favorite foods until you feel less fear about it. I also had a fear of medication and I had to rationalize with myself about it. You can make it through this. Practice deep breathing, and talk about your fears. Get some self-help anxiety CD's and use them. They really work. Fear is just fear. Don't let it win.
