It's a personal feeling that you feel comfortable living, but the ultimate reason is that you don't feel comfortable living because of your emptiness.

You can find something that interests you so that you don't fool around, which will make you feel that your life is full. Of course, it doesn't mean that you play games and dota every day, but find something worth doing, such as learning musical instruments or software, which will help you find a job and enrich your after-school life.
