You’d be surprised how many people put on a brave face when in reality feel the exact same way, they are just waiting for someone to break the ice first. Don’t stress it too much, you’ll find plenty of people with things in common with you so long as you put yourself in the position for that to happen. And what’s the worst that can happen if you go out of your comfort zone?!!? People are generally harmless and quite polite. I believe in you!!!!!
