I can't remember the name of this fic but Sesshomaru started ignoring Kagome and she decides to kill herself, but she wants to wait until after he hears her story through tapes. Sorry if this just isn't a good summary, but it's all I can remember.

Shoot... I was just reading that.... It was an AU story, Sesshoumaru and Kagome were friends and he leaves her to be popular. She leaves him the tapes and he finds out about how she's being abused by so many people... such a sad tale.... wish I could remember the name

Here's one where Kagome video tapes herself.

Videos by Higurashi-San by kazenokoi
Higurashi Kagome is a shy, quiet young woman that would prefer to read a book, or talk to her webcam at home than go clubbing. One day, she meets a mysterious man by the name of "Taisho" at her work who is everything she ever could've dreamed. Can Higurashi-san step it up and gain his affections? Or will she always be that "quiet girl" no one ever notices? Heavy on the angst, with a side of comedy.
