He hates me & I feel like dying !!!

I cussed my boyfriend out because I was upset. We didn't break up but we haven't talked yet he hasn't even been active on social media like he usually would be & I'm so worried I just want to talk to him & make things better I think he hates me. Keep in mind ever since the argument he blocked me, but I guess I cussed him out really bad .... What should I do I feel like dying !!!!
