Looking for a story

Hello any help would be appreciated. So as far as I can remember it was a twilight x luna x celestia story, twilight was dating luna, but put a seal on her own dreams because she didn't want luna finding out about her crush on celestia. Luna and celestia had to force their way in when she went into a coma after saving her parents from a hostage situation. Also remember twilight turning herself into a kitten in the first or second chapter I think.
