Good luck with whatever your choice - without knowing too much about your medical history, I can't really advise
Although, in general, anti-depressants are a good idea if you've been depressed for a long time.
From my personal experiences, I can only say that don't rely completely upon the drugs to help your depression - if you're seeing a therapist regularly, make sure there's a plan to help you with coping skills.
Also, if you feel that something's wrong while on the drug, let your doctor know. I remember trying to ride out the effects of one anti-depressant but instead it drove me almost off the edge.
