Spends two weeks brainstorming on a retelling of Miitopia.

Me:  "Right then.  I believe I may have figured out how to remain faithful to the game's events while allowing room for the main characters to develop, interact, and play off of each other.  I also have a few ideas for jokes up my sleeves.  I just need to begin writing it out."
My brain:  "You're being a complete imbecile.  No one will like your retelling for Miitopia, all you will get is flames and demands for you to delete the story and end your life.  This is the kind of thing that's better off staying in your head than wasting your time to only get insults.  And even if the writing is well-liked, you'll just get burned out like last time by trying to keep up with your readers' demands for new chapters."
Me:  "Thanks for the encouragement."

I do not know why, but every time I fully flesh out an idea I get the feeling people will dislike it.  I usually have a bad habit of abandoning fanfiction when I get constructive criticism due to fear of it becoming the next My Immortal.  I completely realize that the person offering criticism is only trying to help, but I become reluctant to continue a clearly flawed story when I have to face that it is indeed flawed.  And even worse, I fear getting flamed, as I have seen many writers and artists receive insults instead of constructive criticism.

This fear may have something to do with my past of emotional abuse where my mother's ex-boyfriend will insult my works and imply that I will never become a good artist, behind the thin veil of calling it "criticism".  And when I show reluctance with doing art he would simply accuse me of being unable to take criticism.  Maybe I am unable to handle being criticized.

I don't know.  I might type out the story in a Google Doc but I will have to debate over posting it online.
