I'll bet you're laid up for several months minimum, sorry to hear about the accident. When you get to be over 300lbs it may be time to put the ladders away ?
I hope you recover full use of the leg, and can be as you were before. I never fully recovered from a broken ankle, can't run, but can walk OK.
Bathing will be a hassle while cast is on, crutches aren't fun. You'll probably gain weight,too.
It makes you feel very helpless !
Best wishes on recovery !
