Why don't you tell me what's on your mind

This weekend I'm going at my best friend's house, that lives far, far away from me (3 hours). I don't know what I'm gonna do...I'm gonna past 3 complete days with her...I don't wanna eat. I don't want to mess everything that I've done now. I can't eat. I'm just not able to put something in my mouth without spitting it or just take a little piece. I'm not gonna be able to eat in front of her parents. I can't believe that I might be forced to eat...what if I gain all the weight that I've lost...no...
