Update:
My son is now living with me. He's been with me for a few weeks now. He's also working with me. I haven't started being active outside of work yet, but I plan to restart the weekly piano lessons at the music academy soon. I'm looking forward to starting golf and fishing again hopefully this Spring. I've been to the golf driving range a few times in the past 4 weeks.
It still hurts like hell, but I know I can't stop pushing forward.
