Books about fictious disorder on self (aka Munchausen syndrome)

Hi! Looking for fiction and non-fiction books about fictious disorder imposed on the self (aka Munchausen syndrome) but NOT fictious disorder imposed on someone else (Munchausen by proxy). Everytime I try searching for a book list or reading list, all that comes up is Munchausen by proxy, which isn't what I'm looking for.

Thank you so much in advance!!
