I Cannot Do Five 8-hour Shifts

I just can't do it. I had a job where I worked three twelves every weekend, and I got four days off. For someone like me whose lifestyle and interests are unconventional, I cannot do this because the eight-hour shift feels like a 12-hour shift. It's still what 5 of my 7 days a week are centered around. I've realized for my own mental health, I need to find a three-twelve job, again. I even prefer night shift. I cannot do this. I'm sure it's intertwined with my extreme neurodivergence and high sensitivity to monotony? That, my introversion, and my general feelings of alienation that work reinforces those feelings.
