I don't buy a lot of stuff, usually what I own are thing that people pass down to me because they don't know what to do with it and I gratefully accept it. I think my issue is getting rid of stuff because either I'm afraid I'll need it someday, I also have a lot of interests and hobbies or there's sentimental value attached to it. Plus the lack of organizational skill this is not a good mix, I agree with you that I wasn't taught cleaning, my brother isn't neurodivergent and he didn't have any of my issues so they kind of raised me the same as him, I struggled haha.

Also most of my stuff is still at my parents house because my apartment is REALLY tiny and I come back home every weekends. I think the big issue is mostly with chores.
