All those who truly love you would care. Those you know and those you don't know. Those who show they love you and those who kept it to themselves. That's why when a person dies, a lot of stranger may be moved to attend their funnerals. It all depends on the number of hearts you've touched with love while alive.
Finally, if it's suicide, they may not find it easy to forget how you hurt them by taking yourself away from them so soon.
