Teenage life with weird experiences

First of all I'm just 14 so this story may not be properly developed but y'all can feel free to share some of the things I need to know to keep up with my inspirations.
So,this is mainly centered on the life of a high school teenager who experiences weird situations and suffers from trust issues.She feels a lot of things that she gets fed up of bottling up and decided to create an imaginary best friend who she sees as a confidant.
