If anyone suffers or or knows someone who has anerexia, I need help answering some questions.?

It's for a health project I have to do. What its like to live with it, any special needs required, life expectancy, or how this person feels?If anyone suffers or or knows someone who has anerexia, I need help answering some questions.?
These people feel fat! That is so crazy to think that but they do, they look at them selves and see things that a normal heathy person would not see. Sometimes they think that they are so horrible that they dont deserve food, alot of times it takes over their whole life and the family starts to suffer. The life span is very low and they risk body organs shutting down and death at any point in time.
I don't think here is the best place to ask this question. Could be seen as offensive. Well i see it that way. Maybe it's just me.
i had a friend who was anerexia. she was constantly obsessed with her appearence and weight. she would ask if she looked fat and she always looked at the package lables before she ate it. they are depressed usually too.
