Women above 20, im 18, what changes by the time you grow up entirely?

i am currently in high school. and only recently have i realized in less than a year ill be living on my own as an adult I've always dreamt of being. but i dont feel like one. but i want to. how do you act? how do you talk? what do women in that position do? i want to act more like you so i can help myself grow, as i am a person of identity and i need direction. what advice would you give to your younger self? I don't know. anyhting is apriciated. thanks.
