I'm both I guess. When I could still take the bus I was totally an introvert and I would not talk to anyone even if it was someone I knew. I am very quiet meeting new people and I will not leave the house for fear of talking to other people. I can manage going to my doctor and pharmacy if I take some extra klonopin first.
However if I am hypo/manic I go into severe extroverted mode and evryone thinks I am insane.

Introvert or extrovert still nobody likes me except my wife.
