Moving out / living alone?

Hello all. I’m a 20 year old living with my parents and i want to get out of here. I just don’t understand how anyone is supposed to actually live in the world. Essentials costs what seems to be a unreasonable amount, most jobs are boring and based on a Neurotypical lifestyle, i was never taught how to cook and now if people try to teach me we both get upset with each other and nothing gets done, school of course never taught me taxes or bills or what a mortgage is, Im someone who really prefers to be alone completely most of the time, and it’s just all an enormous stressor for me. i can’t understand why anyone would want a job. i understand i need a job but why have a job that makes me depressed and worn out, then i feel ill be stuck like that forever because the need for money never goes away. I just don’t understand and im so tired. The city i’m currently in drains me so quickly and not to mention it’s expensive as hell. The places i want to live are way cheaper but still a lot obviously. How does anyone do this? How are we supposed to live and not just survive?
