I dont know how to word my question... So, i have this plot. I've had this for a few years now and I write on it little by little when I get the inspiration. I've made an outline and everything for it. But lately, I've been thinking that the plot has become convoluted and takes away from its purpose. The over all plot in its broadest is about change and takes place over the span of a year. As I have it now, its broken up into seasons. My main character goes through a different emotional change in each season. I've mentioned this story on here before, but (as i've hit writers block in my main WIP, i've decided to turn my attention to a WIP that I'd put on hold) its about an 11 year old girl in the 50's getting to know her mother who has been absent all of her life. She goes through feelings of loneliness when her mom moves back in with her and her grandmother. She goes through periods of curiosity as she tries to get to know her mom, periods of anger and depression. Her mom equally goes through these emotions and adjustments. A major recurring theme is water. My MC's mother had her really young and out of depression, tries to drown her baby (the MC). My MC becomes a swimmer and likes challenging the neighborhood kids to breath holding. She has frequent dreams about water, good and bad. Her mother, after being home for half a year, is so depressed she tries to drown herself in the lake and the MC jumps in after her. Originally it was supposed to be about my MC and her mom, but I've added more characters and more plot points (like her dad, and finding a half sibling, and going through her first crush, etc.) Dont get me wrong, I really like my outline and plot points, but as much as i WANT to include these things, i'm starting to feel that they are unnecessary to the relationship between my MC and her mom. I guess my question is, how do you know when to pull back and let that "novel" simply just be a "novella"
