How many more years before I become my own person

My whole life I feel like I’ve always followed someone else whether it was romantic relationships, friends with taste of music or hobbies , jobs offered from friends or family … I mean I feel like I’ve always had things I’ve been attracted to whether it’s hobbies or random interests but does anyone else feel like they have never been their own person whatever that may be? I’m 27(m) and I’m coming to the realization almost my entire life has been dictated by others and I don’t even know who I am or what I truly like because so much of my life has been dictated by others whether I wanted it to happen or not I don’t know what I really like or what I really want to do it seems like someone close to me has always influenced me one way or another and I’ve gone along with it because I liked it or not and now that things have settled down in terms of spending times with friends and relationships idk who I really am or what I want out of this life … really sucks I’m getting crazy existential dread trying to figure my self out from a long cycle or following others and thinking I liked everything introduced by others without being my own person
