Lazy, lazy day

I'm not sure where the dividing line is between resting up and being lazy. I sleep a lot. Granted, I'm a cancer and heart patient with drugs infused every three weeks and pills twice a day. So maybe I'm tired all the time because my health is challenged. But it feels like I'm overdoing it, that I could pull it together, go for a short walk, draw a picture and sweep up the dog fur. Well, I did draw the picture.
