Do I have GAD, Panic disorder, something else?

[UCFguy]

I have terrible derealization throughout the day where I don't feel like I even exist, random heart palpitations through the day where my heart is POUNDING in my chest at 60bpm or racing every once in awhile, horrible feelings of suffocation/breathing problems throughout the day, and some other symptoms. I am now afraid to go anywhere without Xanax in my pocket and afraid to go anywhere that I feel emergency help isn't close and accessible. 5 months ago I was super active throughout my campus, eating healthy, exercising and lifting plenty, and even partying and having a blast. After weening myself off of Cymbalta (I had been on it for 4 years without ANY anxiety or depression no matter the situation) I fell apart and now am on 300mg of Luvox and .5mg Xanax when necessary. I can't really even exercise anymore due to the fear of suffocating... which started in October. Am I on the right medication, what is my disorder, and what advice can I get to pull myself back out of this hole and begin building myself into a sane and productive person who isn't scared all of the time and feeling terrible physical effects?

I take 1mg xanax 3 times a day...last one at night with a 49mg celexa ...I take 25mg luvox every morning. I SUFFER from deep depression and deeper anxiety. Mind races my luvox helps during the day with my mind racing...and celexa and xanax at night  for insomnia. Xanax cause I can't even pump gas without feeling anxiety.

I got off of the cymbalta because I dumbly told myself I was fine and no longer needed it. Then boom...  everything and more came and hit me like a train. After reading that, I definitely have symptoms of agoraphobia. Not good.

as far as your basic disorder I couldn't tell you, but it sounds as if you've started to get agoraphobia.  http://en.wikipedia.org/wiki/Agoraphobia  

That will help explain it.  how long have you been on this medication and why did you get off the cymbalta?
