Some people feel that publicly saying anything other than something good about a parent is disrespectful, but I don't agree. You have every right to deal with what you've experienced in the way that you see fit and simply mentioning the unflattering facts is not shaming at all. Besides, as Annie Lamott says, "You own everything that happened to you. Tell your stories. If people wanted you to write more warmly about them, they should have behaved better."
