If you mean writing the book, then I'm glad I worked on it while going through all that stuff. And, in many ways, adding the book on top of that stress actually helped because it was a thing I could control and feel mastery over while surrounded by other things I had no control over me.
If you mean all of the other bad stuff that happened, well, no I would prefer it if none of that had happened but the universe doesn't seem to care.
If you mean how I psychologically compartmentalized things and the long-term consequences of that... I think I probably did about the best I could have in the situation. There are definitely psychological tools I wish I had had before that stuff happened to me that would have helped (like giving myself actual time to process feelings when I could). But given what I had going in, I think I did OK.
