Lexapro (SSRI) is a good one if the side effects don't bother you. I didn't get any, but some people do get rather terrible side effects and have to switch. I was also diagnosed with GAD and panic disorder and depression when I started it.

Also I have heard that Effexor (or the newer version of it, Pristiq) is a good one. It is an SNRI.

Hmm... Klonopin by itself isn't a very good med because you need it more and more if you take it regularly (tho you probably know this by now). Antidepressants, however, take a long time before they start working, and maybe you could keep taking Klonopin occasionally until you notice an improvement in your mood.

Good luck!
