Im not okay! - If you read this im sorry if i sound like a brat!

My friends ask every time i look a bit sad like take today for example i guess to them i looked super sad, well in a way i was i just didnt want anyone too no. So what i keep thinking is i say im okay but they dont get the hint that iwant to be left alone ... i do no that when others are feeling sad i will go all out tomake the happy again but they dont need to do that to me, because when they do that i feel worse because i feel like i am berdining all my problems onto them, and to whom ever is reading this i feel most terrible i just thought if i wrote this down then icould release something that are bothering me!
I no my friends care about me very much but i dont want them get to close to me i never have. i guess it dosnt help that i am always feeling dizzy and like i am about to colaps! but no need to get into detail ... well i have to go school is ending in one minute and once again sorry if your reading this!
