My friend a few months back was also in a motorbike accident. He
too was touch and go aswell, but he has managed to pull thru the
ordeal and should be fully recovered.
So there is indeed hope for your friend. It will be difficult to
adjust, if indeed he is a parapelgic, but it is still possible to
live a full life as one. There is always a situation that is worse,
not much comfort i uderstand, but i believe the problem he will
face is one of acceptance,anger and guilt.
From experience i find that anger and guilt is the hardest to
handle, i have had clients whom had lost their sight and still
after many years are very angry, making the next phase of their
recovery very difficult.
I have no one to whom to pray to, but as a fellow human being wish
him well
