I have been doing some deep diving on different aspects of writing for awhile now.  There are a number of books in the series from Angele Ackerman & Becca Puglisi. I have posted a couple so far, but here is "The Emotion Thesaurus: A Writer's Guide to Character Expression".  I have the entire series and there is a ton of great content in here.  Unless you are a bit obsessed with deep diving, this is not a book you'll read from cover to cover. It is, however, a great reference book for engaging all of your senses and expanding the "Show, don't tell" methods of story telling.

Trying to write a character reaction?  Look up the emotion you want and read through the entry.  It gives you common behaviors, body actions that show that emotion without the writing "He felt X"

Definitely very handy to have your personal library if you want to grow your writing skills.
