My mom blocked my number after an argument and now my stepdad is also ignoring me. What should I do?

I think they’d be happier without me in their life. Anyway my mom and I got into a big argument about a lot of things Saturday morning and she blocked my number. It was sort of sudden. We’ve gotten in fights before but she never blocked my number. I’m afraid she’ll never talk to me again. :(
