Sure you can change. But like Ken said... don't jump to something else you don't like.
The good news is that Accounting is really a good basis for a bunch of excellent majors.... Such as Finance, Business, Economics even Computer Science is not out of the question, it sounds like you have good foundational skills in computer already.
Think about what you want to do with your degree. City and state management requires a LOT of finance and business and economics experts. Banking careers--- Oh Yeah! you are already pretty far down that path. You want to go to Law School? Accountants are often really good as Pre-Law students. How about big manufacturing firms...Guess what kind of people do Inventory Control??? People with Economics and Accounting skills. If you are a puzzle solver - then Computer Science may be just the right thing!
But your skills could lead you down the path to Insurance, or Marketing, or just a lot of other places
I wish you and your family all the best sir! It sounds like you have a great start.
