A book that deals with the frustration of having family members that need therapy, but never get help so they keep perpetuating negative patterns over and over

Or another way to put it, the benefit of going to therapy or…not even therapy but just questioning your own core beliefs and noticing the freedom that comes with that, and the frustration of knowing the potential of your family members if they did the same. But you know they never will and the sadness that comes with that.

This could be fiction or non fiction, but preferably fiction.
