Candice, good to see you back. 20 is the PERFECT are to nip this problem in the bud. I was well over 100 lbs overweight in HS and lost it all when I was about your age. Of course, gained it all back, but I know you'll be smarter than I was!
So don't despair, this is a problem that can be resolved and fairly quickly, if you put your mind and body into it. So go get 'em!
PS My old eyes thank you for changing to the plain, boring old black font color.
