"It's too much stimulation for me, which is why I end up going to the bathroom! I need time outs! ... I get anxious. I'm terrible at small talk and I have a ridiculously short attention span," she added.
The actress said that she was "extremely self-conscious in public".
"I feel pressure when I'm meeting new people because I'm aware of their expectations. That makes socialising difficult. Which isn't to say that when I'm in a small group and around my friends, I don't love to dance and be extroverted. I am just extremely self-conscious in public."
