I don’t think my friends actually know the real me

I have a decent group of friends. We talk regularly, hang out, and everything seems fine on the surface. But lately I’ve been feeling like they don’t really know who I am. Not fully, at least. They know the version of me that’s easy to be around. The one that keeps things light and doesn’t get too serious. But there’s a lot I don’t share. I avoid certain topics, hold back my opinions sometimes, and don’t really talk about things that actually bother me. And now it feels like I’ve created this version of myself that they’re used to… but it’s not completely real. I’m starting to wonder if that’s why I sometimes feel disconnected, even when I’m with them. At the same time, I don’t know how to suddenly start opening up more. It feels awkward and a bit risky. Has anyone been in this situation? How do you start being more real with people without making it weird?
