When I was a young adult I also had to make the decision to go out on my own and live on very little money while in college and after. I could get comfort and cash and everything paid for if I stayed living at home, but that was untenably dysfunctional. After I was self sufficient and showed I didn’t need them, my relationship with my parents improved a lot but was never easy for me. I learned over time how not to get drawn into conflict by keeping everything I cared about out of sight.
I know the trend these days is for young adults to live with their parents, and it’s true things are more expensive. But I lived with room mates for years, then in a 2 room suite with shared bathroom, and I didn’t ride horses. When my mother left home in the 1940s she lived in actual boarding houses. The idea you somehow require a semi luxury proper one bedroom apartment with granite countertops when you are starting out is very new.
