My wife has ms. I am worried about the future. We have no one to rely on. I have mobility issues my self. I bought a stair chair for our basement we’re the washer and dryer are but now it’s not working . My wife is tired and sleeps a lot I work 10 hours a day 5 days a week to make ends meet best as I can. Lately she has been haveing memory issues and has made up memories about neighbors ect. I need help I am working and cleaning and careing for my wife who seams to be getting worse. She didn’t eat unless I make her or have things she loves. I don’t know we’re to get help or what to do I am scared she is the love of my life
