What do you guys read when you are struggling?

Growing up in a chaotic household, I always found comfort in books. Fiction, poetry, non fiction books about the brain and other cultures... Now when I'm depressed I can handle poetry and fiction, but when I'm feeling anxious or mixed I just want to read about mental illness. I guess I'm grasping for explanations for all of these confusing feelings.
Have you read anything that has been of comfort? I very much enjoyed Madness by Marya hornbacher and An Unquiet Mind by Kay redfield Jamison. These things have made me feel less odd and alone.
