Adulthood Sucks

Ok, I've recently been spending a lot of my time on discovering how to be a mature adult. But in all honesty...today is one of those days when I want to be anything but mature. I feel like shit and look like it too. My teacher pissed me off and I missed a test because my entire body feels like one giant ache. And on top of that, I received some life altering news that has me practically in tears. Would it be so wrong of me to revert back to childhood for just one day?
