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?
