I know how you feel! All my life I’ve been hearing from my family that I’m fat and I’m going to achieve nothing in life. Don’t really know what to say but I suppose you could try to sit them all down and tell them that their remarks are hurting you and that you are not going to accept this sort of treatment. Suggest in this matter that you can just try to ignore their remarks and move out when you’re 18 and then show them how wrong they were! Cuz looking at your profile pic you’re gorgeous and you’re doing we’ll at school and everything so I’m sure you’re going to achieve great things!
