What are some books with mentally unstable characters?

Jessicaaa: What are some books with mentally unstable characters?
I just read the book impulse, and found it to be amazing.
I’ve read other books dealing with mental institutions, and find them fascinating.
Or just characters that are mentally unstable in general.
Are there any good books that are worth looking into out there?
Anything will help! Thanks in advance!
