Book for guidance

I feel like my life is slowly starting to go downhill. And I am not prepared for this change. Any book recommendations that will help me brace for the punch life is about to throw towards me ?

(More info- I have been an overachiever my entire life. I have worked hard and got satisfactory results accordingly. But past few month/year nothing seems to be working out for me. Idk what to do.
