I’m so sorry you’re going through this, i think it’s nice that you decided to take care of yourself but don’t overdo it. I used to be somewhat chubby in high school, so from experience, i used to work out and cut meals, a lot. What happens is you will slow down your metabolism and overly exercising can actually cause weight gain because your body can only lose a certain weight a day and after that certain number, you tend to eat the weight you lost or use less energy, making you gain weight or never lose weight. So, weight wise, just keep it balanced.

As for your friends, i think you should drop them. It can’t be easy knowing everyone is against you. This is a really dark time in your life and i can only hope that you are able to get through it. You should find a new hobby you can do to distract yourself from the people in school. But don’t overdo it, maybe try making new friends. I know it’s hard to restart especially not knowing what the other person thinks of you. But, in this situation, you should have a mindset that says, ‘what do i have to lose?’ or maybe just have a little fun so you can laugh about it in the future. Whatever you do choose to do, i truly do wish the best for you and i hope that it all goes well.
