Disappointed, but also relieved. I've took the day off from work (called them and told them the truth about the situation). I didn't fall asleep until 5:30AM last night, and couldn't responsibly head in to work today.
After the so-maniest night of little- to no sleep, I've decided that it's time for a change. So (partially because of a piece of advice from Sial) I've decided to closely regulate my sleep pattern.
On work days, I have to be in bed by 12 o' clock (max) midnight. And 2 o' clock (max) in the weekends. With this, I hope to eliminate future exhaustion, and hope to return to my former self.
