>The problem is, i can't stop reading or seeing content about books(since I'm depressed and books it's the only good thing i have besides some silly videogames in my life)

Yes, you can. The books are the good thing, read books. Content about books is what ruins your good thing for you, so don't read the content. (So getting off socials, as the others have said is most likely to be a positive change). Or at least don't read the content you're reading now: find/focus on something healthier, like writing your own reviews, making/engaging with fanart, looking up stuff about history/mythology/the author. You'll need to monitor how you feel and moderate the content accordingly, though.

The footnotes are read in a different voice. Didn't hinder my experience at all. There were quite a lot of foreign words, due to explanations about etymologies and what not, some seem shaky, because it's highly unlikely that two voice actors would be fluent in so many languages, but neither am I, so I couldn't tell 100% and this wasn't an issue either. It's pretty long though, so maybe pick whichever format gets you through a lot of text better.

The Left Hand of Darkness by Ursula Le Guin. There's a lot more going on, but we do get to see it from two different perspectives.

Seems reasonable to quit then, but as others have said it doesn't seem very healthy, and you probably should look into why this happens.

The point of most books is also not plot twists, and not solving a puzzle. Have you tried books with very little plot happening, like "In search of the time lost", by Proust? What about literature from times/places with different storytelling tradition, like medieval epics, ancient Greek poems? How do you feel about classics, that everyone more or less knows the plot of? Or would you be able to enjoy a novel if you deliberately spoiled it to yourself first?

But these are stunning! Someone clearly sees the book as a potential bestseller as a YA novel and has splurged on some pretty, appealing art. I do really like the original covers too, they are what drew my attention to the book in the first place.

To answer your question, I do own some books with ugly covers, mostly because they were cheap or the only option. I even have wrapped one of them with paper to hide the picture, hoping I might draw my own cover someday. I guess there is a limit to how ugly the cover art can be, though, depending on how much I want to read/own the book itself and how expensive it is.
