I will reply to more of what you said in a bit but I do want to say that I changed majors to get my RN in nursing. I did very well until anatomy and chemistry- twice. My brain was coated in Teflon. It was really disappointing. So finishing a degree that is "me" I think is better for me in the lOng-run. Does it make more money no. But at this point I just feel I have to do what is in me. And to finish what I started years ago.
