Hi Jane! I struggled with my weight all through jr high & high school too & it sucked.
What did it for me then (and what's working for me now) was a balanced diet with a healthy amount of calories plus exercise. I'm not talking running track or hours of some class that only ballerinas can do -- I went for walks, rode my bike & did basic stuff like stretches & touching my toes & push ups and built up from there.
Give yourself a small goal and a reward when you make it. ASK YOUR PARENTS TO HELP!!!! (trust me on this one.) Ask your mom to keep the junk food out of the house for a week. Just a week. Ask your dad to do the same. After the week is over, ask again. Having a mom who is a nurse can be a huge help to you since she will understand more about nutrition than many other people!
Good luck, Jane
I'm a HUGE Daria fan too since my friend Julian was the voice of Jake...we're both from Tulsa & went to TU together
