Am I anorexia??

First I'm sorry my English isn't good.
I'm Asian girl , 20 years old.
I lost weigh from 93 Pounds
Now I'm weigh 82.2 pounds and height 5'2.
I've count calories and low carb for 3 months.
I don't have menses for 3 months.
I eat 3 meals for a day.Sometime I don't eat dinner.
but now I eat carbohydrate such as whole wheat & bread only at breakfast.
After 6.00 pm I don't eat anything except water.
I do exercise 5 days for a week.

I still feel a little bit fat.
I very hate my legs. I think it's too big and ugly.
I have my big face & cheek.
Sometimes I use to stimulant laxatives pill when I eat a lot (more than 1000 kcal but under 1500)
And I feel very bad when I eat dessert.

I want to be skinny body. I don't wanna be fat.
I want my body look like Posh Spice.
I want to have great fashion & style like Nicole Richie.
I'm very happy when people told me very tiny and skinny.
But when I'm alone I usually sad.
Because I must to control what I eat and I don't eat anything I like.

I'm so confuse. Am I anorexia or normal diet ??
Because I still eat.
