Have you ever been afraid to move forward in life?

just wondering if anyone has ever felt scared to move forward in life? Like when you k ow everything around you is just getting stale and you know you are about to open new doors Nd start a new chapter. Have you ever been so scared that you tried to fight that off or just ignore everything? Usually I am wlcoming chnage but latly I’ve felt scared kinda. Maybe because I’m a young adult and don’t like being on my own haha
