What's wrong with me?

Maybe it's stress, maybe it's the hormones.. I'm not sure why, but i kept feeling like crying today :( Perhaps it's just the emo songs that I have been listening to the whole day too.. But one thing i know is that i am stressed. There is so much work to do, my QE is coming up in 20 days yet i have not started preparing for it. I'm upset with myself that i can't seem to focus and am taking ages just to write a 1000 word essay. Been hiding the last 2 days, so that i can focus on completing some assignments but still can't finish. How did i manage undergrad studies?? I'm sure i had way more things to do.. At this moment i really just wish someone was here to let me grab on to and cry.. :(
