I am very sorry because you are going through a lot. As I told you before, you deserve better. Online, in magazines, on tv, etc you will find a lot of stupid things about people that are different or that not fit in traditional cannons. Perhaps, you can try to avoid reading them, they are not helpful. I support your idea of becoming healthier however, please, allow me to tell you this: you are entitled to happiness, in any size. You are you. This is your life. Your life is worthy. Who says otherwise is an idiot. You will make it. Just need time and some help you are not getting now. Perhaps (and this is valid for me, too) we need to expect things from people that, for whatever reason, will not help us in the way we need. They can't do it, they don't want to do it, they do not know how to, i am not sure. But life is us will make us resilient and go beyond current limitations. I have faith in you.
Sending you a hug
