I honestly have no idea because I almost feel like I'm multiple people.
If I drive for Uber, people hop in my car and I chat really well with them. I can comfortably shoot the breeze with the college students I drive around, and we always seem to get on like a house on fire. If I have to go to some party and I'm a bit energized or have a little alcohol, I'm also good to go.
With that said, I am also totally, utterly exhausted at the end of it all. And they say the determining factor is how much energy other people give you when determining introversion/extroversion.
Forced interaction aside, the actual me just wants to be home and on the computer or whatever. I have virtually zero desire to go out of the house, for the most part. But then that's also in large part due to my unknown condition, which includes permanent fatigue.
