Wish I was a doctor so I could give you some really good advice, but since I'm not, I'm going to tell you what I'd do. First and foremost, I would find a new psychiatrist! That he said you "might be" bi-polar is horse puckey! A first rate psychiarist would KNOW if you were bi-polar or not. Since his first experiment to treat this possible disorder was a total disaster, his solution was to put you on Xanax" You then say he tried Prozac "for awhile." How long were you on that? Did he stop that cold turkey as well?
Sorry, but this guy is sounding more and more like a bad mechanic who just throws parts at a car and hope something fixes it!
I would go to my doctor for a VERY thorough check-up...........you have so many physical symptoms that your psychiatrist seems to be ignoring. Tell your doctor everything you've taken and how long you've been experiencing these symptoms. I don't know much about the meds you were on, and you were on them for a very short time but after 6 MONTHS, it's my humble belief that you should not be feeling any residual effects from them.
Continue with the Xanax until you can see your doctor, and do that as soon as possible. Have him refer you to another psychiatrist............hopefully he's not the one who referred you to this one!
Please let us know how you're doing, OK?
Peace
