I want to be anorexic so badly
That's dangerous. Why do you want to do that?
I used to be made fun of for being fat.
I feel bad you were made fun of for being fat but being anorexic is unhealthy and not a solution to past trauma. Instead of being anorexic you should strive for a healthy body weight.
It's funny you're worried about me. No one cares anyway.
I'm sure plenty of people care about you! They would be happy if you tried to seek help and lose weight in a more healthy way. Don't you worry about your health in the future, because losing weight the right way will ensure a stable life.
