I added quite a few words. 1,371 words, to be exact. It was nearly enough for me to say this chapter needs splitting too, but I don't think I need to. As it stands, it's a little longer than I think most of my chapters were. But splitting it would make two chapters that are a little short.
Most of the additions come from adding descriptions of anxiety and from Maggie finding a tool that helps control it some. I think they are good words.
When most writers revise, they try to cut things, to make the writing tighter. But my rough drafts always lack description. They focus on dialogue and quick depictions of action, so I then need to go in and add things like what the speaker's expression looked like as he spoke, and what it felt like when the love interest brushed up against the main character, and whether the rain was a light drizzle or a downpour that soaked all the way through everyone's coats. I don't usually add as much as I'm adding this time, but most of my revisions do result in longer stories. Since most of my rough drafts are pretty short, this isn't something that bothers me even though I recognize that bloated word counts are a thing to avoid. So far this revision, I've gone from to 52,010 words to 55,807 words. I doubt the entire book is going to grow at the same rapid rate, though.
