its the zanax. You need to wean off it. If you wean off properly you won;t have withdrawal but you will experience a time period of not feeling right with increased anxiety as your brain returns to normal function... it has to do with GABA receptors. The zanax is making you worse. THat's how it works. It creates chemical dependency. Get off that toxic crap now before it's too late, but get off slowly with the help of your doctor.
