I use the 'salami' technique.
Write down the most pressing jobs (the ones that bother you most) and in rotation do a little 'slice' of them each day - or every other day.
It's slow, but eventually, the jobs do get done. And you feel better because they have been.
I understand that lack of energy. I'm on medication (strong opiates) that, together with the pain, knock the stuffing out of me.
It's now evening and I've got to find the energy to go and make the bed - which is King size. I've been allowing it to 'air'... all day! My partner's disabled so can't do much, but he is going to cook dinner as he can toddle around the kitchen with his zimmer.
Things will get better - this too shall pass 
A famous matador gored by bull!
This made me quite teary - but smile too
