You're going to college in about a year, which likely means you're around 17 or 18, maybe 19. It's totally normal to not necessarily know what you want to do or what kind of career you really wish to pursue. A lot of different kinds of opportunities are gonna come your way (not just jobs or stuff like that, but anything). I would worry less about not knowing what you wanna do for a job or what you like to do as a hobby, and more about just having a good time and trying out new things.
It just honestly sounds like your everyday activities seem redundant to you, so add something new. Get a boyfriend/girlfriend, become friends with someone new, join a club/gathering (at school or at a friend's house), etc. It's totally fine if a new activity doesn't work out, just keep at it and try something else.
Also, keep in mind that even if you find a new activity, it's not necessarily a bad thing or a failed attempt if you don't stick with it. I played racquetball for about a year (which is incredibly fun, by the way) and then I never really played after that. I got kinda busy with other things and never got back into it, but I'm totally glad that I played for the time being.
