Suicide is not the answer, just because life isn't good and doesn't go the way you planned that doesn't mean you kill yourself. It means you have to try harder and harder. Fight for what you think should happen. Don't let people tell you how to live your life. Talk to someone if you think life is going bad or if life isn't what you wanted it to be. They are there to help you with all your problems.
