Is weird that I’m scared to turn 20 and I feel like my life .. (OnlyFans)

Is weird that I’m scared to turn 20 and I feel like my life is about to be over because I won’t be a te(e)n anymore and I don’t wanna be old and have to lie about my age like all these other girls? I know this is a weird topic but I feel so old. I mean, I just graduated highschool last year at 18.. turned 19 in the summer and now this year I’m about to be 20????????? Where did my entire life go. My life is over ):
