I totally understand where you are coming from as I've wondered the same thing too.
When I'm depressed I want to do nothing all day!!! But ultramarine is correct - chores are hard to get excited over.
Things have been better since I had my baby, now I have to get things done and be organised or maybe my mood has just been better.

Give yourself a bit of a break. It takes a while to recover from an episode of mental illness so even when we are "normal" it can be hard to get through a normal days work.
