What a terrible , gut wrenching story, pleased you managed to come out alive, and I hope you make a full recovery, I had a horrendous fall from a tree a couple of years ago, I chronicled the sorry saga in this forum.
I had a very nasty fracture of my pelvis, so spent 10 days in hospital, weeks in a wheelchair, zimmer frame, crutches etc, it was a long and painful recovery, and it may sound a bit glib and naff, but photography was my lifeline at times, just to be able to get along to my local riverbank, in a wheelchair or crutches, and to shoot nothing special , it helped me feel alive once more, tremendous therapy.
Here's an X-ray of my hip, showing the various hardware used to put me back together again, 2 years down the line, I'm doing almost everything I managed before the accident, although trying to fasten my right shoe-lace is a right pain.
Get well soon, and get out shooting as soon as you can.
