Planning to go NC with my family

I (18M) from the Philippines am planning to go NC with my family now that I’ve graduated from high school. The reason is the unending pressure my parents and relatives have put on me by forcing me to do things I never wanted to do. Just recently, they wanted me to complete a college course that has nothing to do with my dream career. They also told me that they won’t support me in any way if I ever pursue my dream career. Now I am asking myself if going NC with my family is something I must do. Should I?

P.S. I’m not sure if I can ask questions like this in this subreddit
