Do you enjoy anything at all that might have similar duties/backgrounds to a job? I really struggled with this, because I thought I didn't have any practical career skills. But I loved reading ever since I was a kid and decided to change my major and will now try to do what I can to work in publishing. That helped, because I don't have a lot people I'm close to, so that was just for me. And I feel I might never have people I'm really close to—I have a few friends from school and I'd blame lack of romantic relationships on being too overwhelmed with things at home but I also don't really care—although I am working on developing friendships.

You don't have have to know now or pick something super practical/well-respected, but you probably have something. And you can still explore with classes and maybe internships.

There's nothing wrong with finding motivation from people you really care about, that's good. But maybe it's time to try to start living for yourself.
