Hi (((((((((((Girlish)))))))))))) Welcome
Your English is really good actually!
I'm guessing that since you came here - you think you might be anorexic? Do you have a doctor you can talk to? I think that at that weight/height that you've got some unhealthy eating habits (at the very least), but only a doctor can diagnose you.
I don't think you're fat. I also think you need to talk to a doctor about this. Or someone you're close to? Keep posting here, we will listen.
