Sorry to hear that man. I wish you all the best. FWIW when my wife was 13 a wheel flew off a car while she was walking home from school. It hit her in the head, she was in a coma for 4 months, the Doctors wanted her to be removed from life support....her parents are very religious, she pulled thru and after therapies she learned how to talk, walk and do everything. NEVER give up hope.
