Dear teamemmenracing
Regarding your bouts of anxiety, I recommend less caffeine, sugar and alcohol and more exercise.
As for other people around you being mad, this is absolutely correct and nothing to worry about. It is often quite difficult to tell the sane from the insane and even doctors have trouble doing so , please see Rosenhan (1972) "Being sane in insane places". Take comfort in your 'special' friends, at least if no-one else can see them, you won't have to pay for extra tickets should you wish to go to the cinema/races/theatre/etc. with them, thus making them a relatively cheap date.
Best
Dr Dizz
