I am an introverted boy. I am alone at home, I can't cook by bike, and I live in the countryside. How can I support myself?
You are an adult, and you really need to stand on your own feet. Not only do you need to live independently, but you also need economic independence. Parents can't rely on them all their lives, they must be able to live independently. Learn what you can't learn, and find a job to make a living. As long as you work hard, there is nothing you can't learn.
