Losing weight will not make your problems go away. It will not get you better grades, it will not make you perfect, it will not settle the differences between you and your parents. It will not get you a boyfriend, unless you want one who is more interested in body than in mind. It will not make people like you any more or any less. What it will do is slowly destroy you. It will take away your happiness, your freedom, and your ability to love anything other than your eating disorder. It may cause you severe health problems, force you to drop out of school/work, and distance you from everyone in your life. Losing weight doesn't solve problems. It multiplies them.
