I was diagnosed with depression during highschool, and was prescribed Effexor for it. I only took it for a while, but I think it helped. Certainly talking to a medical professional is a good idea.

In the mean time, finding time for friends and activities is a good way to help keep yourself happy I find. I tend to feel more depressed when I have a period of time when I haven't done anything different for a while.

Also, I find that there's an odd stigma to the notion of being depressed... as if its something you shouldn't accept or admit to. But there's typically a biochemical basis to it, so talk to your doctor and see what they think could be done.
