Social agoraphobia (fear of large crowds of people), plus anxiety and a mild panic disorder. Medication has helped enough in which I don't start hyperventilating when faced with everyday life. I just feel very discomforted.
I think you'd be surprised at the number of people who have/have had issue with this. I have some social anxieties, I don't like picking up the phone if I don't know who it is, I feel uncomfortable in a lot of different situations.
