Nightmares that cause insomnia and sleepless nights

Warning this book contains mentions of self harm/cutting.
This is a fanfiction about me and my brother at Hogwarts school of witch craft and wizardry with some other characters as well that I created and some that are not on the character list down below.
I take no credit for the characters I use and I don't want to be copy righted
thx
this is taken place in the third year.
the character is a werewolf as well as the professor lupin.
this is also written at the time when Harry, Ron and Hermione went to Hogwarts.
there is also a lot of mentions about LGBTQ because I am part of it and wanted to write some things about it like in a similar book I am writing.
