I suffered from depression all my life, and started medication a year ago. I came across this amazing book that helped a lot with my mental health journey. "Feeling Good" by David D. Burns. This book is so cheap on amazon and has almost 7 thousand reviews and it helped a lot of people suffering from depression. Highly recommend it.
Another book that helps a lot with depression and manic depression, "Overcoming Depression" by Demitri PaPolos is a great book as well.
One of my absolute favorite books of all time is " A Thousand Splendid Suns" by Khaled Hosseini. This books talks about the struggle of women in the Middle East. This book will definitely make you cry.
