I agree that you may want to try a benzodiazepene. I also had a hard time dealing with antidepressants and the benzo was so much better for me. They have far less side effects, work very well and quickly, but they can cause dependency. For me it was a no brainer, because I was tired of living an anxiety ridden life, but for others it is a huge deal. Many of the antidepressants are also dependency forming as well. My mother is now trying to wean off of Paxil as we speak and I am afraid that is going to be hard for her. It all comes down to whether or not you can live with your symptoms or not.
There are ways to work on your anxiety without using meds such as meditation, CBT, eating well, avoiding drugs like caffeine, nicotine, and alcohol, exercise, etc. These will all help, but if they don't help then meds may be the final option.
I wish you well! I can totally empathize with your situation. I felt sick most of the time before as well.
