I pay a cleaner $25 an hour for one hour twice a week. Which sounds extraordinary in the context of an MMM forum, I know, but I am ok with it. I have chronic anxiety and depression and generally have way less energy available to do all the things I need to do in a day than your average non-depressive. Plus, an untidy house lowers my mood considerably, and I am prone to acute suicidality, so I do as much as possible to create a world that supports positive mood.
To explain the energy point, I like to use "energy units". So, like, I have 20 energy units to most people's 40 at any given time. I spend 15 of those units on work, like everyone else, but when I get home, and I've only got 5 units left (to everyone else's 25), I cannot bear to waste them tidying and cleaning. Those 5 units are precious to me as they're what I get to use for my creative work and time with friends.
All of that said, my health is improving (in part, no doubt, because as much of my energy as possible goes into getting better). I find that these days I am able to do some chores and tidying etc without becoming overwhelmed. It's likely that I'll be able to cut down her hours soon, and continue to do so until I am managing on my own. That's certainly the goal.
I view the cleaner as a luxury, certainly, but one in the 'health' category. Plus, I should say, I am saving 50% of my post-tax salary.
