I agree - very BRUTAL, but, it is better to have planned and prepared for the brutal circumstances than to have not planned and have to say your last good-byes during brutal times.wow, honest replies but brutal.
i think you prepare like anyone else and then some but you need to stock items specific to her ... catheters, medicines? People with limited mobility are much more susceptible to infections.. pressure sores (bed sores) Pneumonia, Rashes so hygiene, hydration and warmth are important. Not knowing her specific needs it's hard to give much more detail. My suggestion... your best bet, based on the small info is a bug in as opposed to bug out if at all possible. say you bug out and the car breaks down, runs out of fuel, road is impassable and you are half way between BOL and home.
