The only way to get out of being depressed is to not want to be depressed any more. If you are still depressed and you've "tried everything" to get out of it, then it's soley because you still want to be depressed.
I can see you thinking "Hang on a minute! I don't want to be depressed! Nobody sane would ever want to be depressed!" WRONG! When someone wants something it's because they are getting something far better out of it than what they perceive on giving it up. What are you getting out of it? I dunno, that's for you to find, but I don't know of several ideas. You have a great story and excuse to tell people, "Noone understands me, I'm sooo sad and there's nothing I can do about it." You get to be irresponsible and not take control of your life, "I got a job and I was still depressed.

" You get sympathy and pity from people. People pay attention to you. You get to wear white makeup, dark clothes and hang out in malls and parks. You get to be right about why everything is the way it is in your life, and you get to tell people they are wrong when they say otherwise. You get to identify with this sad person you've made up over the years. And you get to crap all over everyone else, most of whom are doing much better than you are.
So which one is it? What are you getting out of it? Why do you like being sad? If you can honestly look inside yourself and find that answer, and there might be many of them, then you can start to break down that pattern. That's the only way out of depression.
For me, when I was depressed I had to fight off the urge to jump off a bridge or in front of a bus. I kept it all to myself though, as I'm quite a personal person, but I definately wasn't enjoying life. I used to go to school, do the bare minimum, then when I got home vegitate in front of the computer until it was time to go to sleep. It was pretty much the worse I've ever felt. I felt abandoned, completely alone, very miserable and that my life was spinning out of control. It was when I was sitting at the bus stop at 7am in the morning, in the middle of the winter freezing my butt off that I thought that even if I killed myself, noone would care. I had a housemate that paid no attention to me, a mother and brother who were too busy doing whatever they were doing to even call, and all my other friends were too busy doing stuff to care. So I figured if I was going to kill myself, there would be no point, so I may as well live to spite the world and everone in it. I wouldn't go so easily into the darkness, and I definately wouldn't go out without a fight, and a lot of shouting. Strange I know. I then made a promise to not kill myself, purely because the only person that would notice would be me, and I'd be rather annoyed if I killed myself. Once I made that promise it was like a crack in the walls around me was rendered by it. I realised it was up to me to make my own happiness, that I alone was the cause of everything and I couldn't rely on anyone else. It wasn't until I had completely given up, and then decided I didn't want to be depressed anymore that I could see the way out. I didn't have any therapy, drugs or techniques to get out of it. I just truely, deep down, got sick of being depressed, then over about 4 months got out of it.
No therapist, drug or technique will get you out of depression, only the deep down commited need to free yourself from it's grip. I'm not saying they won't help, they certainly will, but first you need to want it.
So Chado, do you want it? Really?
