I havent been sleepping to well the past couple of nights, due to my tourettes syndrome, and i work on my feet for long periods of time, and Ive been feeling very tired and my feet have been getting really red and my hands sometime too, i also have anxiety so when this happens i get anxious and weak at the same time, and this has happened before, im just wondering what it might be, and what i can do to help myself out.
