I love this, whenever I was 16 and diagnosed, they put me on paxil and evaluated my eating habits. I think there was a documentary on vitamin deficiencies and the effects on the body but I cannot remember the name for the life of me. I whole heartedly believe hobbies/doing things and getting out help with depression.  I had several friends who were very depressed because they weren't happy with their lives and thought it was spiraling down. A few got out of it by picking up hobbies or going back to college or even getting out of the house. Not saying it helps everybody, it's on a case to case basis. Honestly, it's about finding what works for you as an individual, and actually working to get out of it.
