Your writing can use more of "show, don't tell" approach, and could cut out a lot of unnecessary detail to make it more concise.
Here's a simple edit for example.
I sighed with relief as I submitted my essay. Sure it was four hours past the deadline set, but by now I was sure my Professor was used to my way of doing things. Of course, my professor had likely been sleeping since before the deadline, like any normal person would be.
My bubble of focus burst and I realized my next dilemma: to eat, or to sleep? I completely forgot to do either when I got caught up in my work, and I only just realized how hungry and tired I was.
I was so tired I figured I could sleep hungry, so I started getting ready for bed, but as I was brushing my teeth I remembered something I was supposed to do. “For god’s sake Jennifer!” I spurted out, mouth full of toothpaste, dribbling it all down my face. My scrambling to submit this essay made me forget to make a grocery trip earlier! So, completely out of food, deciding that I wouldn’t be able to deal with a trip to the shops tomorrow morning, I gathered my things, and left on a journey to the nearest 24 hour store.
I locked my apartment door and shuffled about in my bag where I swapped my keys for my phone and earbuds. Listening to radio stations is my way of tuning my brain out of everything else. It allows my thoughts to wonder, and its especially nice to have someone else’s thoughts in your head while walking the streets at night.
It was 4 in the morning.
It was also four hours past the deadline.
I submitted my essay anyway, feeling a sense of relief wash over me. Or at least, what relief could be achieved after staying awake through sheer adrenaline alone. My professor probably wouldn't mind; he must have grown used to my way of doing things by now.
I was too tired to think of anything else but sleep, and went to prepare for bed. As I was brushing my teeth, a realization struck me. In all the panic, I forgot to go to the grocery store! I was all out of food and there was no way I could afford any time tomorrow morning to go shopping. I gathered up my things, cursing all the while, and walked into the night to head for nearest convenience store.
I put on my headphones and tuned into the news. News radio was my go-to for walking the streets at night. The voices were like a companion, and always made the cold, dark nights feel a little less inhospitable.
