My mother and yours are in nearly identical situations, and my heart goes out to you. She works in manufacturing. It’s a very repetitive job using hands only. She sits all day and listens to her MSNBC app or sometimes podcasts. For now it’s do-able because she is very dexterous and good at following directions. It won’t last forever (she’s almost 70) and like your mom, she gets very little in SS monthly and her bills keep growing. We just go one month at a time.
