In a sense, we are all a mixture of personality traits. It’s only when you get to the extremes, where it starts to be harmful, that it becomes a “disorder”.
Then I took piano lessons, practised a lot, and learnt three songs quite well.
Ever since then, when I’m at a party where there’s a piano, I’ve played one or two songs, then spent the rest of the night talking with people about music.
Learning to play the piano has helped me to overcome my social awkwardness. Now, instead of strangers feeling like an energy drain, it’s like they charge my batteries.
My point is that you can have no social awkwardness and be good at talking to people, but still have it be an energy drain.
For example, I can’t small talk with someone if I think they’re boring or if it’s someone new who I just met and don’t trust. It’s a terrible trait of mine because it’s pretty judgemental, but it’s something that I’m hoping to improve over time. Because of this, people’s first impression of me is that I’m an introvert, but I’m far from being an introvert (I really need frequent social contact). It just takes a while for me to warm up to someone.
This sounds more like ADHD.
