I have for the last few weeks been feeling on edge and feeling panic attacks come on every day but they come to nothing. A few days ago I woke up feeling nauseous and tense and got up and lay on the sofa in the lounge and in the afternoon I had a 20 minutes nap (sleep) on the sofa and woke up feeling refreshed and a lot better. Anyway, that night I went to bed to watch some television while on my iPad. The television is on a table at the left side of my bed and whilst browsing the net I decide to move my head to the left to watch a bit of television. When I did this my head flopped uncontrollably forward and I got a sudden overwhelming dizzy feeling which left me having a horrible falling feeling all night and started off my anxiety. I eventually got to sleep with that feeling but woke up in the morning with still that falling dizzy feeling. Does anyone know what this could of been? My head just fell forward as if there was no control from my neck and head muscles and a I got a sudden overwhelming dizzy feeling.
