I'm with CollinsMum on this, university is what you make of it. There are plenty of schools which do not require a specific path, some even allow you to design your own major. And when the subject speaks to you it's exciting not boring. When you find something that working on puts you in that place of "flow" it's the furthest thing from boring whether it's ancient texts or matrices.
Going back to OP concerns, and some of the other suggestions, the mentor aspect is key. Professors typically love interested students capable of working at the level they and their graduate students do, as opposed to the ones who are just there. Check out the DYS stories, almost all of them report struggling to find someone who would work with them due to age but that once they did it was awesome, fulfilling and put them on the path to where they wanted to go.
I would say the big question is figuring out where you want to go to college but also when, given your age. Research the best departments in quantum physics and see what they have, what you can tap into until you do go.
Good luck
