What is happening to me?

After waking up from one of my daytime two-hour naps which usually make me nocturnal, I was ANGRY. Extremely angry. Pounding-my-fists-into-pillows-and-kicking-all-the-shit-on-my-floor angry. My brain felt like a painful numb dead weight, and the most hopeless, loneliest feeling imaginable swept over me, either emptiness or hate for everyone and everything. My entire body ached, I wanted to hurt myself and everyone I know, and I felt extremely nauseated. The weird thing is, it felt like this is how I had always felt and would always feel, and nothing would ever get better. Pure unfiltered hopelessness. I still can't get over it. This is some weird Holden Caulfield shit. Bye bye sanity?
