So I've have been dealing with serve panic and GAD for a year now, I also have some PTSD. Everyday I feel woozy, dizzy, heart pounding, jelly legs, hard to sit up (I'm usually laying down). I've lost so much weight cause I can't swallow or eat (I have to eat small portions thru out the day) I've had an echo, 3 ekgs, blood work &amp; and MRI and I'm fine physically, in fact quite healthy. I'm a 30yr male, it really gets bad when I shower, I feel my eyes darting around/overwhelming like I'm going to black out, my legs are jelly and knees buckle and of course the heart palpitations (which I hate the most),  I've never passed out or fallen in the shower or in general but I can't seem to get it out of my head that I'm fine and that I'm not going to fall. How do you deal with this? I'm also prescribed 0.5 mg of Xanax for when it is serve but I don't want to take it everyday (even tho I can).
