Megan Devine argues that grief is a natural and sane response to loss, not a problem to be solved. She emphasizes that our culture's tendency to treat grief as a disease to be cured is misguided. Instead, she encourages readers to accept grief as a part of life and to honor it as a form of love in its most raw and painful form.

The book debunks many of the myths surrounding grief, such as the idea that there are specific stages or timetables for grieving. Devine explains that these myths often make it harder for people to cope with their loss. By challenging these unrealistic ideals, she allows readers to accept their grief as a unique and personal experience that doesn't need to fit into a predefined mold.

"It's OK That You're Not OK" offers practical advice for managing the physical and emotional symptoms of grief. From tips on improving sleep and reducing anxiety to suggestions for supporting others through their grieving process, Devine provides a wealth of resources to help readers navigate their grief. This practical guidance is grounded in empathy and understanding, making it accessible and helpful for anyone dealing with loss.
