books that will make me stare at a wall for hours

I am 19. I have anxiety and OCD. I tend to obsess on death a lot and the fact it all has to end someday. I tend to love books about death since it’s gives a new light and purpose to that fear. I also love books that have lots of emotions.

I love if cats disappeared from the world, tuesdays with morrie, the 5 people you meet in heaven, a little life, on earth were briefly gorgeous, and more

I would love any recommendations!
