I can't get rid of this nihilistic view I have of the world.

I have a need, a want to be important to the world. But when I think about it, all I am is a blip in people's lives. Everyone is just memories at the end, and then when we die there's nothing. So what is even the point of anything? Why live? why make relationships? But I still have this need to feel important, somehow. I'm going to end up being a memory to everybody eventually. No one's going to be there by the time I die. And probably vice versa. And then memories die. So I don't see a point.
