First, my condolences for your loss.
Second, you said it's your first ever fanfic, and you were looking for advice.
Here's some: Don't let the tagging system (the one that marked your story as boring) get to you.
I've seen a story that was nothing more thatn an author taking one cliche formula after another and putting them together withought even bothering to fill in the blanks, that was full with bad grammer, bad vocabulary and bad language, and yet chapter after chapter got tagged as "Original".
I really don't know how they do it...
