What is a good alternative to marijuana for dysthymia?

This may be a strange question, but basically the only reason i smoke weed for mood stabilization. This has not been a problem until recently when I lost a job over the drug test thing and I had some time and actually tried to study for it. I'm convinced it's dysthymia. What else can I try to treat the symptoms without a)seeing a shrink and b)taking pharmaceuticals? Like holistic/natural/herbal/medicinal MJ in NY (currently not legal)
