I replaced the toilet seat. ADHD made this ten minute job take weeks. The old plastic bolts were too stuck to remove, so eventually I had to go in with a hacksaw blade and cut them off. It required kneeling and bending and awkwardness and pain, but I did it.
Eventually, one happy day, there will come some job around the house which can be done while I'm just sitting comfortably. And there will be much rejoicing. Until that day, there will be much wailing and gnashing of teeth. And swearing, lots of swearing.
