as much as i hate to agree with spear, he has a point.
sweetie, the magic will always be there. theres another chance to go. as for your friendship, i dont know what happend, but why dont you let things settle, then talk about it.
as much as i know it hurts not to be able to go to disney, its no reason to make yourself sick. you are more important than a theme park. i know it sounds silly, but i know very well that it hurts. when i didnt get to go for halloween last year i cried. theres more to my reasons of acting like such a brat, but i know how you feel.
id relax and take a deep breath. maybe things arent as bad as they seem. and if you need anyone to talk to, you know we're all here to listen.
best of luck sweetie and feel better.
