Buspirone, Prozac, Zoloft and Paxil. Though medication, to the best of my unprofessional knowledge, is not deemed a suitable solution to the problem on its own. It is best used in conjunction with behavioural therapy. The medication to deal with the symptoms and therapy to change the way you behave towards the stressor, thus you can actually get better, rather than attempt to sweep the issue under the carpet and let it snowball out of control. You probably know all of this already, but it bares mentioning none-the-less, as I don't like to point people towards medication without further caution. I hope this is of use to you.
Best of luck
