I agree with you! You should be writing your story for you and us, who support you. Well, mainly for you :)
People are jackasses. Someone rated my story once as boring. Just on the first chapter. I have a different writing style than most other writers, so I think that's why. But anyway.
Your story is awesome, and you're definitely NOT illiterate. Not by any means. There's so much worse out there. And it's definitely NOT a train wreck. I rate against those people, cause they don't know what they're talking about. And they're probably just jealous.
You have one of the most popular stories on here. That should be an indication to those idiots. Your story is anything but bad.
People suck, and don't know a good story when they read it.
That's my take on it all :)
