A question regarding majors

Hey guys, I'm not too sure if this is the correct subreddit for questions like this but I thought I'd try anyway.

I'm currently half way through my history degree, and I'm having serious doubts about my choice. I always loved history and I figured I'd do something I'm passionate about so I decided to become a history teacher. A few months ago I got a beer with a former HS teacher of mine and we got on the topic of teaching and everything he said turn me off of teaching and sort of shattered what I expected from the job.

So in short, what options do I have in changing majors? How should I approach choosing a new major? I'm stuck in my head about this and I'd absolutely appreciate any advice when it comes to this.
