I'm a librarian who loves anime, manga, and reading a wide variety of genres.
Another entry in my "dipping my toes into mental health graphic novels" work project. This is very text heavy and not really all that fun to read cover-to-cover, but it does have a lot of helpful advice. And not just for folks with bipolar disorder! I plan on recommending the chapter on taking your meds (techniques for remembering to do it, traveling with meds, etc.) to a friend who's been taking meds for depression for a while and struggles with remembering to take them all. The advice might be stuff she's already tried, but there might still be some helpful tidbits.
The page on being kind to yourself was nice - not just "would you say those things to someone you love?" but rather a whole progression of "imagine saying these things to __" before eventually bringing the responses back around to yourself in that moment. I also liked Forney's modification of walking meditation, turning the experience into a story she found herself wanting to participate in (Basically: "Imagine that aliens have learned that this area will be destroyed soon and have contacted you to use your whole body - all your senses - as a recording device. Any thoughts you have disrupt that recording, so you need to try to just experience your surroundings."). And oof, as someone who has spent the past week struggling against anxiety-induced insomnia, I felt the section on insomnia in my bones.
