Please don't. Ending your life will make you nothing but a number on a piece of paper that lists suicide rates. If you live your life, you will find you can make a much bigger difference. Even if you don't do much, it's better than being a statistic.
And the whole point of living is to be happy. If you can't find happiness, don't give up. Keep looking. It's there, somewhere, but you will find it. It can be hard, but you will find it.
