Ok, I know these can be really annoying, so once I have an answer I'll be removing this :)
I'm looking for a story and I am desperate, I have tried every search on every site I can think of its starting to drive me crazy…
Anyway here's as much as I can remember:
It's a kag/sess
Kagome had disguised herself as a boy for as long as she's known Sesshoumaru, Inuyasha and the other characters, only her sister kikyo knows the truth. Kouga and Inuyasha are constantly fighting over her, still thinking she's a boy, I think they're gay in this one (and towards the end when it comes out kags loves sessh they get together, I think) sessh is about to graduate and kags/bestfriend/secretky in love with him for ages, decides to come out and show everyone she really a girl, dresses in hot lookin girls clothes. Sessh gets angry and yells some horrible stuff at her, kags gets depressed/stops eating/doing things, eventually she collapses in the cafeteria and is taken unconscious to the nurses office, her friends confront sess, who, getting over his initial anger, has come to see her cause he's really worried and loves her back. She wakes up, he confesses happy endings ensue :)
I really hope someone can help :D its well worth the read anyone who stumbles on this and can't help check the comments and see if there's an answer, give it a read :)
