What are the signs and sympoms of anorexia?

I don't know if you have any idea about eating disorders, but I was wondering if you did. What are the signs and symptoms of anorexia? If not do you know anyone who might? thanks

Let me first say: Anorexia does NOT work.
I was anorexic for about 9 months.
and i was ABSOLUTELY miserable.
some symptoms:
sudden weight loss
cold, clammy skin
hair loss
visible bones
after a while, when the liver starts to fail, you get yellow skin and eyes.

Well, first, I would like to state that anorexia is not good at all. It is not good for your body or for how you look. Some symptoms of anorexia are not having the appitite to eat or even if you eat the smallest amount of food, your stomach hurts because it isn't used to food in it.
I have no clue as to why you asked this question, but just as a precaution, anorexia is not good, belive me, i've gone through the first stage and I suffered.
And if someone tells you to start being, forget about that person because they oviously don't care about how you will feel and your future health.

well I think im starting a weight problem im so under weight and it hurts everytime I eat im trying my hardest to force food into me but it just hurts too much and I've gone off most foods, I hardlt ever have an appetite and its awful I used to be a healthy fit girl now im miserable im not doing this on purpose and I really want to be healthy again,,, I hope no1 thinks its cool to be like this because its not,,, im miserable and its ard to recover from it,,, it ruins your life
