Nothing Matters

I see no purpose to life. What is the purpose? To love? To earn money? Family? Success? None of it matters. We as a species could stop existing right now and it wouldn’t matter. It would not affect a single thing in the universe because we contribute nothing to the universe. What then is the purpose to continue living? Why must I build a family? Why must I work? Why must I continue to live?

P.S please answer if you can. This thought is a constant in my head for a year now and is paralyzing. I need to stop thinking this and just need one good argument.
