Have you ruled out all and any medical conditions? JMO, but I would make sure it isnt something else, and several physicial conditions can appear on the surface as a panic disorder, or even social phobias.

Most docs dont want to perscribe valium, or xanax, due to the euphoria it delivers. Ativan and klonopin were developed to not be "habit forming", in other words they dont give(most) people that "high" feeling. You shouldnt have a problem getting a doc to try you on klonopin, they may be hesitant to try Alprazolam or Diazapam. Just keep in mind the half life on klonopin is a nasty one, also remeber that there is no benzo that you will not build a tolerance for. Eventually all social phobias I have dealt with are best treated in 2 parts 1. proper medication and 2. Behavior modificiation(behaviroal science).

Good luck
