Sorry I don’t know your circumstances but “Walking on Eggshells” by Langford has literally saved me.

The only wisdom I can offer: other people emotions don’t have to control yours (despite what they tell you). The best take on this that I know: be like a goose - they don’t get wet, just shake it off.

And take care of yourself!

I recommend the book The Road Less Travelled - https://www.goodreads.com/book/show/254865.The_Road_Less_Tra... ... It's an easy read with a mix of psychology and traditional wisdom that still holds much relevance.

A novel? You sure you're talking about the right book?
