SUSAN::You have correctly identified that your attack of anxiety is a direct attack of the enemy - a Spirit of Anxiety from the devil himself. Susan -  in Luke 10:19 you will find that you have all and absolute Authority over this spirit and Satan himself.  Speak directly to this spirit and using your authority, in the name of Jesus, bind it, command it to leave your body, and cast it into outer darkness.  You will find it must leave immediately.  Remember "Life and Death are in the power of the tongue.: (Proverbs 18:21.  Bill Finley
