Cloud of Worthlessness

So, I'm sitting here at my desk feeling guilty for not having the mental capacity to focus on the projects I'm supposed to be working on. I wonder when I'm going to abandon my Teen/early-Tween sleeping schedule, which consists of small increments of sleep here and there whenever there's nothing else going on. Am I making sense? I feel like my heart could stop at any moment... that's how tired I am right now. I just ate a piece of cheesecake and I'm sipping on luke-warm coffee, trying desperately to bring my mind to a level to which I can BS my way through the rest of the day. Sleep is good for the mind. I need to get more of it. That's all for now...
