Hey so your author here.
 Writing your feelings out really is a great way to deal with life's distress. Fan fictions are just normal stories but what makes them intriguing for people is that they are based on their idols but in reality  they are just normal books with interesting plots. Sometimes you wont even know but the story you would be reading maybe based on the life of one who is writing it. So you never know .
Many people write from their experience so if you have ever read a reasonable fiction and longed for something similar its possible. 
All you need to do is just believe in little magic , its never hurts to hope a bit now does it 💫
