IS 17 A KID?

i am 17 and when i cry my mom always tells me i should grow up and stop acting like a kid but then she sometimes tells me that i'm still a child when i try to do things that are considered grown and it's really making me feel confused. i sometimes feel like a child because i am still a minor in my country until i turn 18 so there's not a lot a seventeen-year-old can do here.
