I have no idea to whom you are addressing. You started this thread complaining that your mother tells you that you didn't do the dishes to her standards and then it morphed into this.

You can stay at home forever if you want. Your mother won't live forever, so I guess you should plan on where you're going to live and how to sustain yourself after she's gone.

Truthfully, most people have no specific "purpose" in life. I get up, I work, I do my hobbies, go out and whatever. No particular purpose there. I take care of my dog and I'm certainly not miserable. I don't recall in my younger years sitting around and wondering what my purpose was. I just lived.
