Yep, as someone who transitioned from socially retarded to charming/confident, I remain introverted and absolutely see the distinction. I used to be quiet and anxious and have no idea what to say. I wore black and kept my head down. Then I got some books and therapy and watched videos to process some trauma I was holding onto. That relieved the anxiety, which relieved the depression, and I started feeling comfortable and secure in my own skin. People can tell, and they love people who are self assured. It's easy to get people to open up to me now. But I NEED alone time, often. I love my alone time; at my apartment, in the woods, at work. But I've learned to love and crave people's attention too, social interaction, community involvement. We're social animals. If anyone's struggling with that, they might have some health issues or trauma/PTSD keeping their brain in a frightened state.
