On the verge of a burnout

When my classes started, I was totally gung ho about them, excited with the tasks and getting them done. I know I am facing a burnout because my stupid persuasive speech is due in 36 minutes and I submitted it 44 minutes before the 12pm deadline. I'm not even proud of it, I hastily wrote it around 9pm, I honestly tried to do it earlier today, but my kids were screaming at each other while my husband was looking after them and they were screaming so loud, I had to abandon my assignment to go see who was killing who. The 17 month old was sitting on my husband while he laid on the 2 years old bed and the 2 year old was just screaming "We don't hit" and doing something that looked a lot like hitting. I had no choice but to intervene, abandoning my laptop on the bed until tonight. It was a hard topic, I wrote the speech and instead of memorizing it, I taped it to a Triscuit box, planted my Flip camera on top of the box and pretended I had a teleprompter. As for visual cues, I used family photos, but my speech still ran 2 freaking seconds short so I clearly should have included more. I figure she can't give me a zero and even if she takes off for it, I would be hard pressed to still not get an A in the class. The point is, all of this logic is irresponsible and I shouldn't be thinking this way, so wha-la, I am burned out. I did my psychology in a timely manner this week, but only because it was easy. I had to talk about what stressed me out... Kids, duh! I jumped at a chance to whine and then as per discussion board rules where I have to post a comment on someone else's topic, I found another mother who whined about her kids as well and totally gave her a virtual high five.
