Well, I always say go with the decision that you can live with in 20 years. Are you going to regret becoming a doctor in 20 years, are you going to wish you had followed your passion, probably. If I were you, I would follow my heart, your parents love you asnd just want the best for you...you have to make the choices in your life, because when they are gone, your life will be what you have mead it...weather they liek it or not
