I'm going to give you my honest and biased opinion. I read this book because I needed to. I was going through a rough time, still am in some ways but better overall.

I had a mentality very similar to Nora's, especially when it came to regret. The book helped me put things into perspective, and by the end I was decently satisfied with the story and presentation.

As is the case with anything, if you're not enjoying it than you can just put it down, maybe you'll get an urge to come back to it or not.
