I’m 18F and need advice.

I don’t really know how to explain this, so I’m going to try the best that I can. I’m 18 and I don’t really have much going on in life. Not many things interest me to a deeper level to which I’d want to pursue a specific career path, I feel like my life has a much greater purpose, but I just don’t know what that purpose is. Since I was little, I’ve always been into music I know how to play the guitar and I know how to play the piano. Also a decent singer in my opinion , I feel like I’m going through a crisis because most people my age already know what they want to do with life but I’m just not there yet or not going at the same speed as everyone else. I’ve also been really into content creating, but I’ve never really knew how to put myself out there, I feel like I’m going through a crisis because most people my age already know what they want to do with life but I’m just not there yet or not going at the same speed as everyone else. I’m not interested in a lot of the “”normal things that most people are and that’s why I feel like I have a greater purpose but I just don’t know how to find that purpose.
