I thought I was an introvert for years, but lately I've been thinking (and someone close to me agrees) that I'm really just a shy ambivert. Given the choice between having alone time or spending time with people I love, I'll always choose being with people I love. I could be around my favourite people 24/7 and not get tired of them, and I'm quite energized around them. But when it comes to acquaintances or strangers, I tend to avoid social situations, and I don't know how much of that is anxiety and how much of that is introversion.
