I feel sorry for you too. We too just lost our kitten that we had before the start of the month. During this month she would have been a year old. She was a very special little cat as she would have a very picky attitude. She wouldn't let anyone near her unless SHE wanted they attention, and she would flip on you in a moments notice. There were many things about here, but we lost her when we found out that I guess she was born with the FLV (feline leukemia virus), and it was hard.
Living with my mom and dad, my mom has had many , many, many animals during my life span and I've endured many deaths of animals, and for some reason, I can still remember every single one of them, as they were literally a member of our family.
Take comfort that she didn't suffer, because the pain of watching her wilt away would have been excruciating. She is still loved, and will be missed. Just keep a few pictures around, and many years later you will still remember all those moments like yesterday.
