I remember some of the feelings you are experience expressed by my mom when my dad passed away. She used to say, "I know I can do it myself, but I don't want to." It was really hard to take on those tasks and responsibilities that were once the domaine of my father. I get it.

I hate the way hassles like finding a cleaner can seem like mountains to climb. The dust bunnies will wait (as @IndianaScott likes to say). Tomorrow is another day to set to the task of finding a new cleaner. You want someone who is responsive.

Good for you for grabbing your walker and getting out to pick up the mail! The satisfaction of doing something helps.
