Replying to Broken bones

so i just broke my heel about 10 days ago skiing. im really pissed it wil take a good 3 months with crutches and limping around. it happened by me overshooting a jump and landing flat. I am still wondering why i broke it so bad (into 4 different pieces) when i was only 3 or 4 meters up in the air. ive been in the hospital since and just watching ski movies, if other people can go off clifs that are 60 feet high and land perfectly fine why did i hurt my foot so bad? so if you have a bit of an explanation to help me i would appreciate it.
