As an adult, you don't have to stay trying to get that major, but instead do what you would like to do. Also, if YOU pay the tuition, then you honestly don't have to give a damn about what they want and don't want. Do what makes you happy and don't try make them happy because in the end, it will just make you feel shitty.
In short, FOLLOW YOUR FUCKING DREAMS, YOU BEAUTIFUL GOD DAMN NUB!
