Speaking as an anonymous guy on the internet, I know what you should do. Go to post #74 in this thread.

It's got what I think is the best plan for dealing with depression. The first step is to check for the MANY COMMON purely medical or nutritional issues that can trigger depression. Step 2 is to try all the non-drug treatments, especially those that are great for your health anyway like exercise, improving your diet and meditation. The thread described something to try called "SNAP CLUB". It is easy and fun and it really works. I think it only makes sense to go to drugs if nothing else works and you are still in really bad shape.
