Body Issues almost to the max

So I have a question...

What does it mean when you are self-concious to the sickening point where you think the following stats are fat

5'5''

120 pounds

36C

18% body fat

20BMI

I mean really? I look at that and think cool beans, but then I look in the mirror and think OMG YUCKY.

I really think I'm fat.

I want to be

110pounds

10%body fat

17BMI

I take two RAGING hot baths a day to try and sweat some weight (That I don't even have mind you) off, I wear layers upon layers of clothing to bed and sleep with no AC& a comforter to sweat in my sleep and I eat less than 1000calories a day.

I am obsessed with the way I look. I am obsessed with my imaginary weight problems.

I know it's sick and fucked up that I'm 16 and I'm the same pants size I was when I was 12, but I don't want to stop.

I actually feel GOOD about the results of my insecurities and issues.

Because I feel the need to be perfect.
Even as I am typing this I am scruitnizing wvery word trying to make sure I make no errors.

I'm so dumb.

But I want to be the percect little barbie doll.

Seriously.

I'd rather be underweight than even a pound over 130.

That's sick.

But I look so damn hot.

Is that wrong?

Maybe, but in my mind, so the fuck what.

I look damn good doing it.
