I am 13, 5Ɖ" and 184 pounds. And advice will help, because I can't handle my weight and if I don't do something I may commit suicide.

Nobody's committing suicide here.
First of all, get blood tests done. If you've tried everything and can't loose a pound, it may very well be thyroid problems, which can make you depressed, overweight-- and it's fairly common. Medication would make an enormous difference.
Secondly, do lots of aerobics and cardio. Don't worry so much about weights and whatnot-- that tones muscle, and anything that speeds up your heartrate is what burns fat. Running is absolutely the best. To build fitness, you want to do half an hour three or four times a week, to maintain, you want two to three sessions. Skip rope is also fantastic. It's hard at first, but after about a week, you'll notice you can go further and faster. Run everywhere you can - to the fridge, to the mailbox, etc.
And you know what? If you're stressed, the best thing in the world is exercise.
Good luck!
P.S - You could also try a vegetarian diet, or drop dairy(and replace it with soy!). But whatever you do, please don't take the suicide way out. It gets better.

Stop playing video games and get outside more.

SUICIDE IS NOT THE AWNSER PLEASE DONT DO THAT !!!! PLEASE DONT! THINK POSITIVE=)

Stay away from fast food. Have your parents take you to a nutritionist for a balanced plan that is realistic. Cut out sodas and try to do something physical, even walking. It's a process. Your body is still growing and you may end up losing some of that fat if you eat healthier.
