Career decision help!

Im a jr in highschool and everyone keeps pestering me about “what i wanna be” but like IDK! I guessss i have an idea but i dont wanna tell anyone yet bc i just....dont....want to. And everyone keeps flipping their shit whenever i tell them idk what i wanna be and theyre like “ooooOOOOHHH BUT UR GONNA BE WAISTING TIME!” And im like “HRKSUBRUSGEH IM 16 likE idk what im gonna do about this pimPLE ON MY FACE” and im just uuugggggGGHHHH idk how to get them to stop pestering me about this! Someone help!

But srsly do i actually HAVE to decide NOW? Its a bit scary deciding what i wanna do for the rest of my life and not second guessing yourself and being completely sure about the career/major decision.....
