Girls, please stop doing that to yourself! Look around you, watch the news, see what it can really do to you, how much it can harm you!
It's not a joke, it's very serious! You can be throwing all your life away, your future career, future family, husband, kids...
I used to be anorexic and at some points bulimic too, i know how hard it is to stop. Even now when i'm totally healthy and my weight is healthy if i sometimes feel i ate too much i throw up and feel like shit about it. Stop while you still can. It's not worth it!
