There are numerous non-drug relaxation techniques available. If you can't teach yourself these techniques, then spring for therapy with a Psychologist. (Psychologists cannot prescribe meds in the USA. Stay away from Psychiatrists because they are pill pushers.)
I taught myself meditation. I downloaded mp3's from the iTunes store on the topic "guided meditation."
Westerners are often turned off immediately by this topic because they have the wrong idea about it. It is really nothing more than breath control. You don't "think about" anything, and you don't contemplate your navel. In fact, the idea is to think about nothing at all.
At my worst I used guided relaxation techniques 2 - 3 times a day. Now I don't feel the need to do it as often.
