looking for books about middle-aged characters who finally catch a break

having a pretty rough time lately and could really use some reading recommendations. been dealing with family stuff and feeling pretty isolated – you know how it is when life just keeps piling things on

what i'm really craving are stories about people in their 40s or 50s who have been struggling for a while and finally get their moment. especially characters who've lost themselves taking care of everyone else or just feel like they've been left behind by life. something where an unlikely person gets an unlikely victory

read eleanor oliphant is completely fine recently and that kind of hit the spot – just want more stories where someone's life actually becomes worth living again after a long rough patch. any suggestions for fiction that deals with this theme? bonus points if teh main character is older rather than some twenty-something finding themselves

thanks in advance
