It sounds to me like your mom isnt a very nice lady. I understand that it is really hard to lose weight when you have no support, but we are all here for you and you dont want to die. Life is the greatest gift and the grass always looks greener on the other side. There are also unhappy skinny people look at your mom she wouldnt say that to you if she was happy with herself. If i was you I would stand up and tell her that you dont appreciate her rude comments and that this is you and she should love you no matter what!
