Things I would tell the skinny teenage girl on the left, if I could:
Don't worry so much, everything is going to be okay.
Skinniness eventually will be an asset, and yes, someday you will grow b**bs.
Someday you will have a man who adores you and the most beautiful children on earth.
Your sisters will someday develop a great fashion sense and you'll be proud to be photographed next to them. (giggle)
It's okay to be smart, keep studying hard and don't obsess so much about being "popular."
And......I promise, someday those glasses you so despise will be the height of fashion.....really.
Everything is going to be okay.
