Did i break my leg from snowboarding?

i went snowboarding last week for a very long time. im an expert at snowboarding(not to brag) but i fell on the halfpipe while doing the backside 720 and i think i broke my leg, because when i walk it hangs down, and i cant control it. ive told my mom, but she always ignores me, and the only way i went snowoboarding was because my friend got 2 free tickets to blue mountain. i went to the doctor and he said i probably needed an x-ray, but my mom wasnt there when i went to the doctor, i sneaked out because the family doctor was beside my house. even though i proove to my mom about my leg, she wouldnt care, because she is always out anyways and she gets drunk everyday and smokes too much.
