Ok since it seems like a lot of threads on here are very similar I'm just going to list some of the more common problems that pop up on here and their solutions. If your problem falls under one of these, do us all a favor and don't post.
I'm in middle/high school and I'm depressed.
We all were, it's natural. Just try to relax and not let the pressure of the social situations get to you. I know it may seem like that first break up/failed test/embarrassing moment is the end of the world but trust me, its not. Roll with the punches and learn never to take anything too seriously, otherwise you'll just end up with an ulcer and a nervous twitch.
I think I'm going to kill myself
If you're somewhere between 13-19 and you're saying this then put the razor blade down, turn off the my chemical romance and realize that whatever problem you have right now is trivial in the long run. Your parents not getting you a car/ not letting you go to a concert/ making you take off your eyeliner is not a good reason to kill yourself. Yeah I know I know, searing darkness of your soul and goth poetry and so on, its still not worth it. Refer back to the first point about being depressed in middle and high school. If you're 20 and over or don't fall into the whiny emo category then I suggest waiting a year. Its pretty good advice to wait a year before doing anything life changing just to see if it still seems worth it, whether it's getting a tattoo or buying a house or lopping your genitals off for the masochistic fun of it. During said year I suggest going to a psychologist to at least talk the problems out and see if that helps. But, if after all that time you still feel equally as terrible as you did when you started then hey, it's your life and your choice.
There's this girl I like...
Ask her out. No, no shut up, Just ask her out. Yes I know its frightening and you don't think you can do it and you just shat out your spine in utter terror but ask her out. This doesn't mean confess undying love to her or immediately try and get into her pants because both are rather creepy, though the second might actually work depending on the girl oddly enough. Asking her out isn't about making her like you, its about letting the two of you know each other better and seeing if there is in fact a spark there or if it was just infatuation. Never go into a relationship or even a casual date trying to be something you're not, because you won't be able to keep it up forever. Be yourself, if she doesn't like it then it was never going to work anyways.
There's this guy I like...
I know theres a stigma in a lot of societies that girls can't ask guys out, but fuck that shit. Guys like directness, not coy half hidden messages or dropped hints. Its not that we're stupid and don't pick them up (though we do miss them some times) its just that we're not always sure that what we're seeing is really a hint or is just our hopeful imaginations. If you just come out and say it I guarantee 90% of guys will be much happier for it. Also, as much as I know this will be ignored, for the love of god, don't try and go out with someone because of good looks alone. This goes for guys too obviously. I know the temptation is great but in the end you'll have a much more fulfilling relationship if you go with personality first and looks second.
I have this rash/oozing boil/compound fracture/my head is on fire
Why the hell are you asking us? Do we sound like the type of people who are medical professionals? Don't ever ask the Internet about health problems because its basically the same as walking up to anyone on the street and asking them "Does this look infected?". If its some minor problem then don't worry about it, your body will fix itself 99.98% of the time. If it's major though just go to the damn doctor.
I'd like to lose weight
Exercise and eat healthy. I know, shocking concept eh? These days everyone is looking for a fast, painless, easy and effective way to lose weight or gain muscle and I hate to tell you that it doesn't really exist. If you really want to lose weight you're going to have to work at it a bit and actually get off the couch, jog around a bit and stop eating cake for breakfast. Low fat, low calorie meals, regular physical exercise, drinking plenty of water and having a regular sleep schedule are the best and most health ways to lose weight and get fit. So man (or woman) up and get to it.
I'm afraid of...
The best way to get over a fear is to understand why you're afraid of what ever you're afraid of. If the fear is rational (eg fear of heights because you might fall and injure yourself) then the best thing to do is to take every possible precaution and then face your fear. If you're afraid of heights then do some safe things up high and you'll probably at least dull the fear. If your fear is irrational (Fear of mariachi bands because their hats remind you of giant nipples) then its probably best to ask yourself "Why am I afraid of giant nipples?". Regardless, the best way to conquer fear is to understand why the fear exists at all. Once you know that you can start to work on getting over it.
Thats it for now, more may be added later. Hopefully this is satisfactory.
