When is my limit?

I am freaking tired today!!!!!!!!
WHAT THE HELL!!!!!!!!!
I am emotionally down!!!!

SPENT around 12 hours in school!
FOR the CHANGE concert!
I was doing the sounds...
And you know what
I did many mistakes and it sucks!!
Damn stressful!!!!

Besides that, my schedule is like tightly packed and many things else need to do...
Sienzzzz....
I can't breathe.
I really need someone whom I can talk to.....
However, there are no suitable person for that.....

Once i passed my limits... I do not know what will be happening to myself!!!
