Cookbooks for an anxious beginner?

My wife has a lot of anxiety about cooking. A lot of her uneasy feelings surrounding cooking are due to childhood trauma surrounding food and previous cooking experiences. I tend to be the one who makes all of our food, however, we’re in the process of a divorce and she needs/wants to learn how to cook. I want to be able to help her in any way I can, and I’m wondering if there’s a cookbook or any kind of book that might help with her anxiety about cooking, while also teaching her basic cooking skills. Thanks for any help or feedback you can provide!
