That sounds a horribly difficult situation. I don't know what I'd do in that situation, especially as it sounds as though your parents live too far away for you to be able to help directly. Like several of the other posters here, I think that it might be worth investigating a mobility scooter further. I think that these can sometimes be funded using the motability scheme (it sounds as though your parents might be eligible on the basis of disability, though there's quite a bit of paperwork if they haven't already done it). Alternatively, it's often possible to get second hand scooters. Taxicard, dial-a-ride, online delivery and local charities are all excellent ideas as well. Might it be worth trying to speak to someone at the local Age Concern to see if they have volunteers who might do basic tasks? Otherwise, social services can often provide home help, who can do bits and pieces around the home as well as picking up shopping and running small errands. Citizen's Advice Bureaux or Age Concern would be my first point of call - they should be able to point you in the right direction, if nothing else.
