I have just posted another message before yours. Even people with anorexia do eat, so if that is what you're thinking, that is not correct. I have children older and younger than you, and my experience with this is because it happened to me. and I was 40 at the time. You need to get some professional help, because you may be doing irreversible damage. You can damage your organs, You will or become or probably already are anemic. You will become very tired. I am 5'5 and weight was 120. That's not a pretty sight. Please talk to your parents or someone that can help you. You should not do this to yourself. You can e-mail me at email@example.com if you need more information. Good luck to you, and pleas take care of yourself.
