thank you for your thoughtful reply, LT. i think i should elaborate on my initial post. my wife is 6 feet tall and weighs around 250 lbs. 2 years ago, she lost her right leg under the knee. she has a prosthetic and can walk, but only short distances, like from the house to the car or the car to the Dr.s office. she usually comments that it's very painful to walk. she went through therapy, but i don't think she remembers much of what they taught her about walking.

i am unable to pick her up. i am trying to make some kind of plan for when - or if - the time comes when she can't walk at all.

i wonder if there is some government help available, in some way?

things are well enough for right now, but i know things will change.
