Hey, I've been in a very similar situation myself. I am majoring in Psychology but my mom had wanted me to major in computer stuff. I'm not interested in computers as much as I am with Psychology, so I stoodup to my mom and I told her I am going to major in Psychology. And now, I'm currently proving her wrong that I will not get somewhere wih a Psychology degree. The reason for that situation is that my mom majored in Psychology but did not persue it because of her mother.

You just gotta know what your passionate about and it sounds like you do. Just follow your dreams and you'll get farther. Just prove your mother wrong. You'll be happier for it than if you did what your mother wanted you to do.

I hope this helps.
