One approach would be to take a complementary major, since you'll already have the job experience. Electrical Engineering or Mathematics come to mind. Another approach would be to indulge whatever else you're passionate about, be it Philosophy, History, Literature, or whatever.

I studied Physics and ended up in this industry without any formal CS classes. I would have liked to get the formal knowledge of Algorithms, Programming Languages, and Operating Systems. Perhaps a course on databases. I'm glad I took the EE intro course on digital circuitry, and I'm glad I took the math course on graph theory. I think taking a lot of math courses is a good idea.

So all of those in the previous paragraph are my suggestions for courses to take. The other point I'd make is that college can be a lot of fun. You're around a lot of other people of the same age, and everyone has a lot of free time and not many responsibilities. College has value outside of just knowledge acquisition. But it's not for everyone, and it's fine if you decide not to go.
