I don’t know what I want to do with the rest of my life

Soooo I am 21 years old and I have two kids. I’ve worked in restaurants my whole life and worked up to a manager position. I haven’t gone to college full time but my parents really want me to have a degree. I’ve dabbled here and there in a few things but I honestly don’t know what I want to do with the rest of my life. I can’t think of any job that I’d enjoy doing for the rest of my life and i feel like I’m failing my family. Is there anyone else who has gone through this and has advice?
