Um yeah, dat me. My tendency to do that is born of low self-worth, poor diet, exhaustion from capitalism-related horrors, frustration at my lot in life as a trans autist, and indignance towards the billionaires and the bigots enabling them.
How to snap out of it? No god damned idea. I'm so close to being able to pick up and move from Texas to Portland (if I can just get offered any one of the two dozen teaching jobs for which I have applied) where I hope that my mood spikes up a bit because of the locals and the locale. Apart from uprooting my entire life, I genuinely don't think there is a way for me in particular to escape this rut.
Good luck to you.
