Dream job

So my goal is to become a psychiatrist after high school...which im pretty sure alot if you know that it take 12 years to become...now my family is telling me i should just do something that only requires 2 years an it will be faster an easier..which honestly i really want to become a psychiatrist.. thats something i want to really do i have been dreaming of becoming a psychiatrist for 4 years now an im still head strong into becoming it but now i feel like i have my own family telling me it may be hard for me an maybe im not going to make it but saying it in other words of course...i dont want to become something else an not like what i do an it would obviously kill me because thats not what i wanted to do or become...any help with confidence ?
