I need help with depression?!

First of all, you need to calm down. Take a deep breathe, sip some water, and listen to quiet music/read a book.

Do not give up on life, life is like a game, sometimes you lose, sometimes you win, who knows. You are in a very young age, and I'm sure your doing fine in school. It's okay, because think of all those people your age that died, for giving up on life, committing suicide, what a terrible idea it is to harm yourself, it really hurts thinking about it. You need to be brave, and courageous, and stop being so negative, you really do seem negative about most things. I recommend you to see a therapist to clear up your problems. Make sure it's a therapist that will actually SOLVE your problems, and not swag it around the dust because it's nothing, because it really is something. Your therapist will most likely set aside your problems, and solve 'em for you. I wish the VERY best for you, and support you.

You may have a social problem with your parents.
