What a great idea that you can read about here.
Dear Me (1985),
I know that your life seems to be mostly over now. I am writing to tell you that all this will just be a bad memory someday. Those friends who you cherished and who let you down (and refuse to sit with you in the lunchroom) will only be remembered in the past. That group of girls who are so popular and make your life miserable (think Mean Girls) will marry too young, have babies, never finish college and grow very bitter.
That little foster sister that the state returned to her natural mother will grow up to be a beautiful young lady and you will see her again.
The trouble your brother caused your parents will be seen later as not as bad as it could have been. He will marry well and have 3 children for you to be an aunt to.
Quit trying to be so different. I know you want to fit in badly and your response is to stick out. None and I repeat none of this will matter in 20 years.
You will survive high school and will find college a whole lot more fun and enjoyable. You will meet someone who will love you and (gasp!) you will have children. Just hang on and try not to take everything so seriously.
