sigh Where to begin...
As someone who has read fanfiction in addition to published literature for many years, I feel I can safely say, that this story, while not the most original, could at least be amusing to read for a few minutes. However, any charm it could hold is stripped away by the spelling and grammar errors. (99% error free? Are you not reading the same story we are?) Complaining about the negative feedback in these reviews while not seeming to attempt to fix the listed issues shows a lack of caring for the reader. Have someone else proofread and edit your story before you share it and you will most likely see more positivity.
Best of luck
