Some people are naturally small, so I'd think that those folks could look okay that size. If a small size is not normal for a person, that person will have to starve to reach it and then would look sick or scary... But you raised a good point, the mind DOES play tricks on us. I see someone that I think looks good and then hear others call that person too skinny or anorexic. So my judgment about what is a healthy size/weight is not good right now, and sometimes it's hard for me to know when I am thinking a too skinny person looks okay. Back to your first question: if size 0-8 is not normal for you, you cannot be healthy at that size. Take care of yourself! Hug!

we are conned every day by media to what looks good.
They do it cause they want our money!
Its all lies ,
They have put a image out there for us to aspire to ,so they can sell us stuff while we are trying to attain it.
Dont buy into it anymore, they dont care if our lifes are ruined or even worse we die,
long as they have our cash,
Magazines are big business,
Dont buy them they kill people especially women.
Treat them like poison,
Rebel be you.
We are not just bodys, we are wonderful , complex human beings, who are here to share their lifes with each other, and be kind and compassionate to each other,
Thats what makes life really matter not how we look.
Rebel, eat 3 meals a day, eat foods you like, you decide!
And your weight will eventually stabalize to normal level for your height.

If you have anorexia you will need proffesional help first, so seek it out.
Choose life, a life consumed by eating disorders is time wasted,
Believe me i wasted years and years.
