Books with heavy life themes that made you feel gratitude for your life

Have you ever read any books with heavy life themes that ironically made you feel better or grateful about your own life?

Having recently read "We Need to Talk about Kevin" and "Revolutionary Road" even though they have heavy themes about family and relationships, ironically, they made me look at my own life and realize that thankfully I'm no April nor Eva. However their stories reminded me of real people who went through (or are going through) similar situations. I understood them, empathized, but didn't see myself in them. Which ironically made me feel grateful because I could have been like either of them if I didn't made some hard choices.

And unlike both of them I truly love and don't idealize my husband in a toxic way. Many women I know fell and still fall into this trap and end up repeating patterns with different men over and over again. I couldn't stand neither of the Franks in the stories, as they are an example of men who need validation through raising a traditional family with little regard to the feelings of their spouses. Makes me wonder how many women (and men, for that matter) are stuck on these types of toxic dynamics with kids in the mix.

Somehow reading these 2 books was like therapy for me. Especially in a stage where I'm my 30s I feel I'm not the same person I was in my 20s. Reading these stories made me really think about my life and it made me feel a lot better for what I have now that I could have lost if I made bad choices like April and Eva.

I know there might be heavier books in this regard, but these are the two books that really stuck with me this year. What about you? Has any book made you feel this way?
