I have some suggestions but they are all fiction/YA books. Would that genre be okay?

No, thank you. I read books like that (I study early neurological development) so I'll do some research on them.
And yes, the fiction/YA recommendations would be great as well.

Great. Here is my list (sorry its long):
“Courage in Patience”- Beth Fehlbaum
“Because I am Furniture”-Thalia Chaltas
“Big Fat Disaster”- Beth Fehlbaum (This is one of my favorite books ever but it is seriously heavy. Focuses on how emotional abuse plays a part in a girl’s depressed and suicidal thoughts.)
“By the Time You Read This, I’ll Be Dead”- Julie Anne Peters
“Invisible”- Pete Hautman

Thank you!

There's a book called "Not Without My Daughter" by Betty Mahmoody you might like, it's a movie too

This might not be what you mean but the book split is about a teenager who has a dad that is abusive to his mom and him it's about him overcoming how he was raised to try and be a better person

Its fiction, but "Graceling" is kinda like that

It’s not exactly mental illness or abuse but Marching Powder is a pretty incredible book. It’s about a jail in Bolivia, I learnt a lot about different lives people lead and stuff they get themselves into. Definitely opened my mind a fair amount. Or if you want something of abuse in a different format and the effect it can have on the human mind, Helter Skelter is a classic. Written by the lawyer in Charles Manson case, and surrounds everything, makes you consider the absolute mind fuck he had on all his followers
