Is it okay to be lost in life ?

I just turned 19 in October. And I feel lost in life when I tell people that, they look at me all crazy like I’m suppose to be in college like I’m suppose to be doing something. I did go to College but I stopped going but I was just tired of school after doing 4 long years in HS. I really do wanna become a nurse but I also wanna do hair. When I try to tell my friends how I feel and if it’s normal to feel like this they don’t really know what to say. Have u girls gone thru these experience before ?
