I was prescribed benzo's at a young age and I'm sure If you really pushed for it, you could get yourself a script for Valium/xanax/clonazepam. I agree with those on here that recomend cognitive behavioral therapy. I've mentioned before on this site that I had very serious OCD when I was younger, and what got me out of it (or at least for a good while-the severity never came back) was a combination of SSRI's (Zoloft-generic is called Sertraline) as well as an awsome CBT doctor. At the time I of course attributed my recovery only to the Zoloft but looking back, after years more of anti-depressants which didn't work for other very real diagnosis, I'm more skeptical of SSRI's, and place more value on Cognitive behavioral Therapy.
It's not a quick fix, but the ones that stick generally aren't. I would give it a try first, but if the anxiety is really unbarable a good medication that is not nearly as addictive as benzo's would be gabapentin. It's actually intended for neurological pain but it's prescribed offten off label for anxiety and mood disorders.
Once again we aren't doctors, so I would really recomend trying to find a good psychologist first and have them asses your symptoms. If they think you need medical treatment they can refer you to a psychiatrist.
