What should I do if I am fat and ugly and always laughed at?

Then stick to lose weight, exercise more, and don't skip meals. Skipping meals will only ruin your health. You can't stick to losing weight without eating, but you can't eat too much now. Hold on, this thing can only hold on! I don't think you should have a big skeleton on your face, but you should be fat or let your hair down. And study hard, make achievements in learning and increase self-confidence. Don't say that you can't live, but you must believe that you can change!
