Welcome back on congrats on surviving your ordeal! Its hard to believe how fragile life is.
Even our bones break easier than you think. My tibia snapped just by putting some pressure on it at a bad angle during a hard bike ride in 2011. I found out how fun crutches are and by the time I was healed I enjoyed using crutches more than plain walking. I could move very quickly with them even run up stairs with them once you learn how to use them like a swing.
I still have a plate and seven screw in my right leg, the xray of the hardware is actually gruesome.
