me angry

S0 weird, I have been in a really good mood all day..and all night since I got home, but now, at 11.30pm i'm lying in my bed all mad. Angry. and not just a little angry..Feel like I wanna kill someone, but I don't know why? maybe i'm too tired.. But now im too angry to sleep, i'm already worrying about tomorrow morning, I'm not known for being all happy and cheerful in the morning..

Hm maybe I do know why I'm angry.. I don't know, ..
