I think this will cure you, but you may not like it.
1. You will have to give up all juice and stimulants including caffeine.
2. Serzone is a good choice, but make sure it does not change your weight -- many gain bad weight on it.
3. Wellbutrin SR may be a good choice as well. I might consider it before the Serzone because you have tried many SSRI's and not responded.
4. You will need a benzo like Xanax -- the one I prefer -- or you can look into the others. Make sure if you try Xanax you get strong enough tabs -- doc's act like the stuff is heroin.
5. You must begin weekly talk therapy.
6. Look into light therapy search for Apollo light box. This is helpful.
I realize this is a lot of work, but unless treated aggressively, anxiety tends to get worse and can become debilitating.
Please keep us posted on your progress.
