What sort of books could I enjoy outside of dystopian sci-fi and true crime?

I’ve mentioned that I have issues with anxiety and rumination and even going down rabbit holes where I’ve started believing in some conspiracy theories, and someone said maybe I should lay off True Crime and dystopian fiction which does make sense. I do feel bad with how autism really narrows my interests, and my interests are the dystopian classic Brave New World (also liked other books like Fahrenheit 451, and I Have No Mouth But I Must Scream) and true crime about cults, narcissistic parents, and mad scientists, also been trying to read Frankenstein. They said I should probably read something that’s more uplifting, which makes sense, but Im worried that I’ve just completely rewired my brain to just not respond much to feel good materials. Suggesting a nice book about dragons or something might be like suggesting earl grey tea to a meth addict

What complicates things further is my research for university at the moment is adding elements of genre fiction mirroring our world for a magical realist comic anthology I’m making, so I kind of have to read sci-fi and horror that mirrors our world. (I should a
also really read some fantasy, it would expand my horizons by a lot). Horror probably never can be that good for my brain, though I suppose something old about ghosts or zombies or witches won’t be too bad.Suppose there’s other ways to mirror our world other than though something gritty and it’s on me to open my horizons more. Someone suggested Ursula Le Guin if I’m doing a project on sci-fi
