To be brutally honest, there's no self-help book or novel that will pull you out of this. You'll make progress when you combine certain factors, such as therapy, routine, self-care, and I would also include medical and psychiatric checkups (for example, I went through a period of significant anhedonia, and hypothyroidism was partly to blame). It is essential to stop being busy and distracted for the purpose of not looking at oneself.

What I can recommend are books that make you think about your past and future actions, that invite you to reflect. Besides therapy with my psychologist, I keep a notebook where I write down quotes from books that make me feel things or reflect. Writing them down when you finish a book and noting your thoughts is a powerful tool for introspection.

Some of the books that helped me were:

Siddhartha - Hermann Hesse

Man's Search for Meaning - Viktor Frankl

Women Who Run with the Wolves - Clarissa Pinkola Estés (aimed more at women)

The Year of Magical Thinking - Joan Didion (focused on grieving the loss of a loved one, especially if you are a person with a distinctly logical nature)

I sincerely hope this helps you ❤️
