Something happened yesterday that made me really upset.Should I tell someone?

This boy named Dylan Oldham who's bullied me previously found out that I reported Keisler and then he called Keisler over to the table and told him what I did and told him my address and told him to go there and beat me up and kill me.I was really scared that Kiesler was going to beat me up and do something to me.I don't know what to do.And I know he really said that to him because I heard him.I need to tell someone but I'm too afraid to.Should I tell someone?

Omg thom kick this kids ass already, yes tell ur folks

Yes, of course. Tell your parents or your siblings or just someone elder who could protect you.
