Why can't I just be thin ?

Why do I feel like this? Its so annoying - why can't i just be thin? why do people who want to be thin can't and people who don't give a toss just can't no matter how hard they try?

I feel like my tummy sticks out too much and i just want to tone and get rid of it but its always there why won't it fucking go away ! :'( How can people not say its big sometimes?

I know its not 'massive' or 'obese' obviously : i'm anorexic ! But its still not good enough for me i need to change it now ! but no-one will help me :@ Please come back soon periods so everyone will concentrate on helping me be happy rather than healthy ! aaarrrgghhhhhhhhhhhhh
