Not sure you are still following your thread, but if you do, what about taking a break from all workbooks, shirt to reading good fiction, and see if you can relate to emotional ups and downs of personages/characters/heroes in the books you read? There might be a character similar to you, who also has struggles with anger, and by living that character's life in your mind as you read and reflect on the book, you might be able to help yourself more effectively than with sheets from workbooks. This is just one idea for you.
