So, here is what happened while I was feeling so bad. First of all, I slept, but my head didn't stop hurting. In fact, it got worse—it felt like a tight hoop was placed around my head, pressing into my temples.

Secondly, I fell onto the floor several times for no apparent reason: the first time in the hallway, and the second time in the kitchen. I've been having random bodily spasms/twitches, and out of nowhere, random parts of my body start hurting—right now, my earlobe and my finger are aching (I don't know why).

I feel dizzy and I'm starting to see visual glitches. For example, I was watching a video of a blonde girl in a white and blue outfit, but when I looked back, her hair looked black even though I thought it was white. When I rewatched the video, her hair actually was black the whole time...
