Am I being over dramatic?

So my stepdad and I have a lot of fights normally but not like this. We had a big fight and I guess I have sensitive ears, cuz if someone raises their voice I consider it to be yelling. So we were fighting and I was telling him to not yell at me and he was. He started telling me that it's wrong for me to think he's yelling, and it's wrong o me to perceive things the way I do. He also says I am procrastinating everything. I got up and told him I was done with the conversation because to me it seemed like he was telling me it's wrong to be, well, me. He's yelling at me through my door now and I am refusing to come out because I don't want him to insult who I am. Am I being dramatic? Is he being mean?? Sorry but I need someone else opinion on this. Thanks !
