Unfortunately Phobophobia can create a vicious cycle as those with existing phobias are predisposed to develop Phobophobia as a response to the negative effects of their other phobia. This is called anticipatory anxiety, which causes increasing fear in the time leading up to a planned confrontation with the object of fear.
