Is living a fulfilling and/or happy life just cope for our mortal existence?

We're all gonna die anyways, and in time, everything we do will just be forgotten. Nobody's gonna care about us unless we become famous, and even then if enough time passes or evidence is destroyed, they'll be erased too. I know it seems nihilistic but this isn't reall my own viewpoint, it's those of black pillers.
