What will it be like to stay at home alone 15 to 20 years old?

I will stay at home for a long time and have less contact outside. When you go out. I can't integrate into this society. Will gradually become withdrawn. I don't want to talk to anyone. I just want to be alone. I used to be willing to move, but now I don't want to move. I just want to lie at home. Now that you are aware of this problem, make a change. Go out for a walk more when you are free. Take a walk and feel. I stayed at home for three years because of illness. Really getting more and more withdrawn. I feel depressed because I don't want to get in touch with others. Now that it is good, it is necessary to make changes. It's good to get out more and get in touch with the society.
