dear Katekate ,
If you have no history of seepwalking it is very, very unlikely that you will suddenly do this , try to think back why this bothers you , was it a film or article you saw or read , I bet you are like me , each time I see a health programme , I'm convinced that I've got everything going , I don't watch them any more .
Next time you get this anxiety , say to it , ""I don't want you , I am not going to listen to you . I am now telling you to leave my mind .""
see how that feels kate ,see if it helps .
take care dejavu
