Of course I’ll reply! Sorry, I replied late, though :( I have to try to check my messages more often!
Hm, I see how this situation is difficult. Although you’re feeling jealous, don’t do anything to your friends and have them break up. Let them do their thing, even if it hurts you a bit. Consider the thoughts and feelings of your girl-friend!
As for your weight, if you’re feeling insecure try to remind yourself of things you like about yourself. If you want to lose weight, just do little excersises here and there, even if you do sit ups while watching TV, or run up and down the stairs it could make a difference! It’ll also give you that little boost of confidence. Don’t compare yourself to your friends, though. We all come in different shapes and sizes!
Hope I helped, xo
