I'm not sure exactly who Mercedes is in 'my 600 pound life' without more information. She could be a patient on the show dealing with obesity - related issues.
Since we only have the title 'my fault novel', it's impossible to tell who the author is. There could be many unknown or emerging authors with such a title. It could also be a self - published work by an amateur writer, in which case it would be even harder to identify the author without more research.
Well, without more context, it's hard to say precisely. 'My fault novel' could potentially be a story about a character who constantly feels that things are their fault, perhaps in the context of relationships, like a person who blames themselves for the breakdown of a friendship or a romantic relationship. It could also be about a more general sense of guilt in a larger story setting, such as in a crime - related plot where the protagonist wrongly believes they are at fault for a crime they didn't commit.
I really don't know. It could be inspired by real-life incidents but transformed for dramatic effect. You might want to check with the creators or do some research to get a clear answer.
Well, without more context, it's difficult to say. It might be a novel where the main character is always in the right, or it could be about a utopian world where no one is at fault. Maybe it's a new take on the concept of faultless existence in a fictional setting.
