As LifeRecovery mentioned universities oftentimes offer very affordable counseling (and you don't necessarily have to be a student there). In my town we also have "the women's center" (just google it) that offers very affordable counseling. The problem with these places is that the waiting period can be very long (I waited probably 5-6 months to get into the women's center and the waiting list was even longer at the university).
All in all, I've come to realize that the best thing to do to fight depression is getting out and doing things. Which is easier said than done! I had to drag myself out several times in the past and it's not always working so well for me (I have a tendency to isolate when I'm down). Also all types of physical activity (sports, yoga, running) can be a mood booster.
This too shall pass... you'll get through this and will get better in time! HUGS!
