I used to have pretty bad depression. (as well as a few other negative things) I found that when I am bored, it is worse. So I made it a point to always be doing something. I would go for a walk, or ride a bike whenever I'm not feeling so well. Try to not be alone. Constantly find time to be with people. Music is a big one. I used to be really into Korn. All their songs are self detrimental. a friend of mine turned me onto Power Metal, which is all about courage, and freedom. (There's nothing wrong with listening to negative music, about violence and such, just don't let it be towards yourself and your own emotions.) The music you listen to really does have an effect on your well being. I used to think I needed a girl to be happy. No sane girl will want to be with someone who will bring her down. So you must learn how to be happy by yourself. Most importantly, (this might sound a little new age kooky) But your thoughts are the biggest thing here. What you think, is what you get. It you believe your going to be sad, then you will be. If you believe you are fine, then you will be. In fact, I even told myself "Everything is great! I have no worries" I was obviously lying to myself. However, once you keep telling yourself that everything is good. Eventually you will start to believe it.
Check out this blog about thinking positive. This is the main thing that helped me realize all this. The person who wrote the blog is Kyle Cease. He is a funny comedian (my favorite personally), and he actually won the standup showdown a few months ago.

Check out his other blogs too. They help so much!
He's not just a comedian, kind of a novice motivational speaker, and has some great audio and video
The journey out of depression is hard, but the best thing you will ever do!
