Can I cry?

Cause I sure as hell want to.

I've been in bed since 12:30. Lights out since 1:45 ish... it's now almost 5 and I have not slept for more than a half hour at a stretch. I DON'T KNOW WHY!!!!!!!!!!!! It's like my freaking brain just cannot shut down and it's PISSING me off! I am so TIRED! I want to sleep for like five hours... or two hours... just a decent stretch so I don't feel like such a zombie. *sob*
