Anxiety: Anxiety often leaves one disconnected and poorly focused. When a person has too many worries or concerns (stress), the mind will attempt to withdraw; this is experienced as a fuzzy feeling in the head. Some folks get tunnel vision. Feeling unusual like this often compounds the problem. You begin to worry about your health in addition to the other sources of stress.
