Look in your Yellow Pages under "mental health" or "counseling" for free or low-cost clinics, or therapists who work on a sliding scale. If there is a major university in your town, oftentimes the psychology dept. will run a community clinic as well.
Also, depending on income, you can get meds for free through this program,
pparx.org . You will need to see a dr. to get them prescribed, though.
Good luck.
