Let me state it clear: some people in those forums have to get up at 5 am and work 8+ hours per day. When they come home, they are mostly tired as hell. Working is much more stressing than school yet did you see anyone complain?
You think you are the only one who had problems at 14? Yes? Then you are wrong. When you grow up a bit, you'll see that everything you mentioned now is sh*t compared to what will come later. People from all over the world come at those boards to discuss. "Discussion" doesn't mean one must read your whines.
If you really want to speak to someone about your problems, I'd reccomend speaking with your parents. Most of the time, they'll help you or give you an advice. How can anyone here help you? They don't even know you! The time it takes you to type your whine, you could spend trying to improuve the situation.
