Stress and lack of sleep make my symptoms a lot worse.. Ironically, although I am a neontatal intensive care nurse, my job doesn't stress me.. I can function ok at work, although I am overstimulated most of the time with the alarms, phones, babies crying etc.. My stress comes when my electric or water is turned off because I didn't pay the bill.. and the time my car was reposessed a few weeks ago because I didn't pay the car payment (even though I had more than enough money in the bank!). Under stress I get worsening headaches, difficulty finding words, difficulty concentrating on tasks at home and work, easily distracted, lightheaded ness, easily overstimulated etc.. If I can keep the stress at bay after a few weeks I go back to my new norm (for past couple of years) of still having symptoms, but more tolerable..
