You have accomplished a lot! And it seems your current school values you and is supporting you every way possible… there is something to be said for being the big fish in a small pond. If staying at Mizzou is your fallback plan it certainly seems it could work well for you based on the information you provided and the links to majors @collegemom3717 provided. Overall, it sounds like you have much to offer any campus.
I’m not an expert on transfers so I will leave specific advice to others. I do wish you success and happiness and hope you find the right fit (including financially)… even if that perfect fit is exactly where you already are!
