Is my big toe broken?

me n my friends were walkin n i tripped on the curb n felt my toe crack. now its been like a couple hours n is only gettin worse.wen i straighten it it straightens in two motions instead of just straightenin normally.it barely feels colder then the other ones.my parents wont take me to the doctors. is it broken? n how can i immobilize it so i can walk with less pain? cuz i need to play a soccer game.
