it feels like bugs or warms are crawling in my head, and they move round my body. i feel better after i get some rest, but anytime i engage in studying or any activity that requires using my intellect the crawling sensation give me severe headaches. if i am emotional or upset, i experience an uncontrolled outburst and movement. since the crawling sensation started i am forgetful, in-composed and inarticulate. i also experience extreme tiredness and i am usually extremely sleepy.
