Take life one day at a time. Worrying does not help. Try not to worry about the future. Remember that you will not be in school forever. Remember that most of your teachers care about you and want you to learn.
Most parents love their kids and want to help, too.
But most of all, remember that you are special. No one else is like you. Look inside and see all the good things. Do not take yourself too seriously. Learn to laugh at yourself.
