Finish my Masters or take a break year before post-bac?
Don't stay in a graduate program you're not happy with. It isn't worth it if you can instead work toward something you're passionate about and can make more money while doing it and likely won't be judged heavily for doing, especially if you haven't even spent much time in the past year on graduate studies. At the very least, if you have a good advisor, discuss your options with them. They may be surprised to see you but will likely not encourage you to stay in the program if you aren't dedicated to finishing it.
