Hi Stardust,
Welcome. Xanax is addictive so doctors are careful about giving it out, but they do give it and closely monitor it. My daughter is on zoloft and uses xanax as a backup in extreme situations. It has to be used with caution so one doesn't become addicted to it.
There are numerous medications for anxiety. It takes time to get the right combination that works. It takes a lot of suffering through side effects too.
Keep talking to your doctor. If he doesn't help you, go somewhere else if you can. Psychaitrists are the best bet for medication issues.
Hugs,
MG
