My incompetence hurts my parents and myself, and I can't do anything. My parents are 60 years old and still working. I don't feel well, okay?

Parents have their own way of life, so don't blame yourself. It is not too late to work hard from now on. If you can, you'd better get a job first, and then start working first. With a job, your life will be colorful. When you have income, you can buy something to honor your parents, even if it is small, parents will be happy for your self-interest. Moreover, life needs to be accumulated, and few people can succeed at birth. Therefore, if you change some inherent ideas and make a life plan for yourself, you can read and study more when you have time to increase your knowledge and wisdom. As long as you are willing to work hard, you will certainly get something.
