Lack of sleep

What happens when i lack of sleep--->it kinda leads to a super fouled mood YiYi~
well..my face turns black n scary..i dun feel like talking to anyone much more than smiling to anyone..
I can't even bother to reply much sms-es or calls..even if i did..my tone is kinda rude..=.=
Ok..1 thing i'm taught is that..i shouldn't throw my temper at anyone who has nothing to do with it..
but.................................................................it's so hard to do it when i'm tired
i just shoot anyone who come close to me ._. so it's time to STFU ba..till i recover from insomnia~
