In your posts here, and wherever else you've written, you have a wealth of kindness, thoughtfulness, and a treasure of life-learning that would make a wonderful book.
If you don't yet think of yourself as a 'writer', you could visit your local authors' association meetings a few times, and find a member who appreciates your style and is looking for a project.
Formal book publication is a long arduous process, even when your subject and style are as desireable as yours.
But self-publication is much easier. ...Perhaps one chapter at a time.
