Hi drjbeam,
I'm sorry about your mate, I guess some people just never face the fact they are going to be in a chair for life, I always say to people who ask "you never accept it you learn to face it and carry on" 27 is too young to die and i saw a guy with a pressure sore on his thigh you could fit your fist in ! i couldn't believe what i was seeing, how does someone allow that to happen to themselves, and i guess there are no easy answers every person is different and has different things going through there minds that we just cant fathom.
Good on you for being his carer, I became my wife's carer in the last 10 years of her life and i look at it as being a privilege that i could help her and try to make her life a bit easier. It takes a rare kind of person to do that for your friend and i would shake your hand and say well done, and i know just how you feel after they are gone. I feel the hardest thing i ever had to do was to carry on after she passed and to be honest i think that was harder than when i had my accident 30 years ago aged 18, But our daughter dragged me back from the brink to where i am now. Good for you drjbeam i bet it has made you a better person in the end.
