i have a friend who has a very specific and weird problem. whenever she makes eye contact with someone of higher authority, her head shakes really quickly and it doesn't stop unless she looks away...sort of like if you really tense your neck your head starts shaking, but a little more severe. because of her job, this has turned out to be a real issue for her. she works at a large company and has to meet with a lot of different people. she figures this is some sort of anxiety issue or something, but couldn't find much info on people who suffer from this exact thing. has anyone else experienced this or know of someone who has?
