It's the minority way to do it but you might want to try role playing in third person. Rather than "I run at the goblins screaming at them 'Come fight me you cowards!'", you'd say "Weebles runs at the goblins, screaming at them...", etc. Some people find it easier and less self-conscious to have that layer of separation between them and their character. And it might seem less "weird" to other people if it's clear that you're not screaming at the table, but it's just your character's personality (not saying they should think it's weird but just offering suggestions).
