When my husband is really bad I cook him breakfast in bed. Then I drag him to the couch because that's where we hang out. I don't care if he sleeps there but at least he interacting with us even if it's to be rude. He could be depressed, it could be the meds but I don't think it's laziness. I feel people naturally want to be productive and be social. I always suggest That all couples with chronic diseases seek both individual therapy and couples therapy for extra support. If there are children in the house they should also be in therapy so they have a trusted 3rd party adult to help them develop coping skills for when their parent is sick.
