Importance and reliability.
You know no matter how bad my MS may get I can rely on my Brothers, one of which also has MS, to need me for any problems they have with technology. Feels good actually to have a use outside of space heater / food eater and just little brother.
My mother in law moved in with us, and I feed her breakfast, and do her laundry, and change her bedding. It really gives me purpose, and feels wonderful to be needed/useful/necessary. Well done, you!!
