Randomized Anxiety

I was literally doing fine earlier today until something hit right after my volunteer gig and now I just feel jittery. I truly don't know why. I was eating dinner with my family earlier and I felt kinda dizzy and like the whole room was too bright and now I'm okay but the room I'm in is currently darker than the main room and it feels much better. Anyway, I'm just trying to do work right now but these feelings of anxiety are making me really unmotivated and tired so I'm kind of just..straight up not having a great time. I know I need to finish this project but I'm just bleh.
