Honestly, drawing is one of the best things I can do when I'm upset. It helps me focus and take my mind off whatever it was that upset me. Even if the things I draw when I'm upset aren't intended to be "some of my best work", they usually come out better than I expect. I think part of the reason is simply because they have some sort of driving emotion behind them. But, I really do like the second drawing. That expression is just... honestly wow.
