I have tons of non mentally ill friends who do the exact same thing. I wouldnt call it laziness - just inactive perhaps and low on motivation after dealing with children and chores. Maybe some nice self nurture stuff will have you feeling a bit better. A foot spa, facial, meditation or yoga etc. How much do you exercise? The less you do the less energy and motivation you have. (I struggle with that at times too and I dont even have kids to deal with).
