I understand a lack of motivation. Things get done around my place when they're at a point that I HAVE to do them. Laundry stacks up until I've run out of clothes that don't smell too bad to go out.
I'm currently keeping myself busy with busy work. I have a media collection and miscellaneous computer files from over the years to organize. I'm probably over doing the organizing, but it makes the days go by faster.
Not sure I have advice, but I do understand.
