I walk funny or weird if I get anxious. I can't tell if I am walking really fast or just normal unless someone would point it out to me. I really walk fast to begin with but it can be awkward when I feel like I am rushing to get to somewhere but why am I in a hurry? It is hard to take leisurely walk when I am in a state of panic. I guess it is the usual sudden rush of adrenaline that gives me the "fight or flight response". In my case, I choose the flight response because I am not really in actual danger but just panicky.
