Oh my god….It isn’t your fault dear. Everyone has issues. Maybe he has some you don’t know too! I think you should try to see if you can try and fix this. You  could get therapy from a professional to get better emotionally, and with the weight, my mother is a fairly large woman, but I love her to pieces, and no one will judge you most of the time! Just be who you wanna be! He probably didn’t want to hurt your feelings. I hope you are at least having a good day, and i really hope you feel better!
