Now I find myself at a loss

I need a night to unscramble my thoughts and get back into the game.

Yesterday was my last day of official classes. As my English professor was talking, I felt regret. I regret that I didn't put my all into it, that I didn't take in all the words and read all the stories. I regret that I couldn't fulfill my potential in that class when he was amazing and the material was thought-provoking.
