This is a reply to Faith but it's actually aimed at foreveryoung. I want to second Faith's advice to find a good councilor; they can be a real blessing (I'm speaking from experience).
But that might ought to be step 2. You probably should see a doctor first to see if your depression has reached the point where medication is a good idea. If you are clinically depressed, counseling without the medicine is not typically as effective. And if you are severely depressed, you need medical help ASAP.
