Books that get your mind off things when you’re depressed? (but also a picky snob)

I'm in a very iffy period of my life and really need to get my mind off things. Unfortunately, I'm a picky reader. I adore fantasy like the witcher books (especially "the baptism of fire", the characters are peak), ASOIAF, some thrillers like Drive your plough over the bones of the dead and boys in the valley. Two genres I specifically avoid are YA and romance, I just have not enjoyed them (no shade to those that do). Are there any books with immersive worlds, that are well written and utilize some element of mystery to keep things interesting, y'all could recommend to me?
