It seems like lately I have a pattern of 3 recurring mood stages:
Stage 1: I am deeply annoyed and angry for no particular reason and everything just makes me bitter
Stage 2: I don't give a single shit about anything, good or bad
Stage 3: I am overly excited about something, usually fandom stuff
As a good tradition, after being excited for a few hours and not finding any outlet for it, I pass onto Stage 1.
