My spouse is a bed ridden invalid on oxygen and I need to be able to take care of her, but I am older (with a bad knee) and on a fixed income, and without a car it is extremely difficult. I am asking for help so I will be able to drive to the store for food and supplies, and to her doctors. I just can't do it anymore. Thank you all that help. Anything that you can share, even $20 would help so much.
