I spent almost the whole day writing, but a lot of it was editing and light revising. Some of it, though, was actually writing brand new passages.
But I last worked on this book so long ago, I need to go through from the beginning and refresh my memory, before I can write new chapters. (Some of those new chapters are going to be inserted between those I have already done, since they involve different characters, but take place at about the same time.) Since even the revising involves putting new words together, I find that encouraging, after so much time in the depths of a clinical depression, where even writing a grocery list sometimes seemed like too much effort. Also, some of the chapters I am reviewing are better-written than I thought they were. (That is the problem of trying to write when you are suffering from depression. It can be impossible to tell the good from the bad because everything looks bad.) So that may mean there is less work to be done than I thought. Perhaps. At least I have never gone through a period of depression that made bad writing look better, so I think I may be getting well.
