I know that my mother has eating disorder and my twin sister have eating disorder.

I know that my younger sister and my father doesn't have eating disorder.

I don't know about my grandmother.

We were raised in the similar environment, but why only I, my mother and my twin sister have eating disorder and why my father and my younger sister don't have it?

Addiction issues

I am addicted to alcohol, drugs, chocolate, sugar, food, internet and sleeping.
What is the cause of addiction?

If you already know that it's a problem, you should go see a psychologist.
