Shy

Wanting to talk to people, but being too anxious or awkward to. Possibly to a point where your body physically won't allow oneself to talk to people.
I think what explains shyness best is, "Being shy isn't cowering in a corner and not wanting to speak. Being shy is wanting to speak every moment, but not being able to." - Bo Burnham, 2018

I state this as someone who is very anxious and shy myself. Thank you for your time.

I want to talk to people so badly, if only I wasn't so shy.
