I’m sorry you’re feeling like this. You’re not alone, I have been there. Personally, the app/site GoodReads helped me. Reading reviews on books, finding books you may have liked and seeing similar titles, or seeing what people are also reading that read your liked book. Or perhaps taking a trip to a book store. Have a coffee and browse the aisles, new titles, etc. I think once you find one title you love, you’ll feel out of the rut you’re in.
