I was outlining and making notes for another novel in late August/early September, and had a rough-but-workable outline prior to my adventure at the hospital. During the past few days I've been looking at that outline and filling in some ancillary information--the protagonist's physical description, rough descriptions of key locations where multiple scenes will occur, and so on. I've not done much that might be considered "creative," but, at this point, any progress on any writing project feels like a major improvement in my well-being.
I think I've finally found the optimum times of day to take my medication so that it has the least impact on my ability to think clearly, and I've been exercising a little more each day, taking short walks in front of my house followed by ten or fifteen minutes spent on a bench in my front yard so I can enjoy fresh air.
I'm still frustrated by my need to rely on other people for shopping trips and the like, but now that my mind is free to imagine people, places, and events that do not exist, it's almost like I'm free to travel. After all, most of my adventures prior to surgery were the ones I took in my imagination and then put on paper for other people to share.
