Maybe you and your grandmother could do weight watchers together. I've known a lot of young people your age have great results doing this. I use to work in pediatrics and adolescents. The doctors always supported weight watchers for younger people like you, because you can eat alot of things that you like as long as its in the range of points for the point system. You may also have to get your Dr. Approval for this. I hope that maybe this helped a little. I know its very hard when your trying to lose weight. Hang in there hopefully things will get easier. :)
