Wow I totally relate to your book smart issues. I am also considered by friends and family to be incredibly smart. Yet I'm the messed up one with horrible mental health problems. While my parents don't throw it under the rug outright, there is this theme in my family to not acknowledge it too much.
My brothers have their successful lives and I'm just suffering. I also know that my parents enabled me so much too growing up and I never grew the skin needed for an OK adult life in this world.
