I need help

My parents all my life wanted to grow up to become a doctor, I agreed and went along with it for years. The thing is, my passion is not in healthcare but in crime. The way I can sit down and investigate crimes or psychology for hours because I enjoy it so much, shows where’s my passion really is. My grades are not super low overall but my chemistry and math marks have always been my lowest, around 60% or a C. My parents are aware about my marks, I’ve tried tutors and studying for hours as well but it is just not clicking. My parents also want me to take my SAT even tho it is not required for my country, they want me to open up opportunities for me. I know they mean well, but no matter how hard I try my passion is no where near what they want me to become. I’ve tried to talk about this to my mom at least and she said it’s too risky. I know it’s a little risky, but I’d still like to try my best to become something I want. My grades for my other classes are great, around 80% or higher. I’m not sure what to do, it’s all stressing me out and really affecting my mental health.
