Hi Frances and welcome.
I'm old enough to be your mother. Who am I kidding? I'm probably old enough to be your grandmother....so here's a bit of grandmotherly advice.
It would be fabulous to take care of this now...because believe me, you canNOT ever get those years back. And high school is a special event in one's life...a real milestone, actually. And when you get older, you will indeed realize that these years are not a "practice" for when you actually start your "real" life. I think it was John Lennon who said "life happens while you're making plans" and he was so right. Unfortunately, how right he was doesn't really hit you until you're older......and you look back and go what the heck happened?
And this doesn't even factor in how much being overweight affects your health negatively as you get older. You're young now and have NO idea how tough it can get years from now if you don't take care of yourself. Being overweight can cause not only all sorts of chronic health problems but also eventual painful conditions due to putting so much weight on our weight-bearing joints. The sooner you take care of this, the less damage can be done...that will manifest itself years from now.
You have a fantastic opportunity here so please take advantage of it. You are so young and can fix this now and it will pay off for you so much in the long run. You just don't realize this now as much as you will when you get older. When people get older, still overweight, painful joints/back can make it difficult, if not impossible to exercise and then they're stuck with having to lose the weight strictly via dieting. Becoming sedentary can make you even more overweight and then you feel trapped and overwhelmed.
You're young and healthy and this is SUCH a great idea to do this now...believe me.
