My husband has a chronic illness and frequently spends weeks in the hospital. I have been doodling each day while sitting with him and many of them reflect my thoughts at the time. Often appearing are desperation, hope, frustration, sarcasm, fear.
Doodling is what I do. It's a way to make visible the randomness that's in my head - just drawing out a concept right when it comes to mind and scribbling on whatever I can find.
