Other times something dreadful has happened. For example, the person may have seen violent death first hand. She may be unable to get the image of it out of her head. She may awake petrified from nightmares. She may be irritable, jumpy, cold and distant with her loved ones.
Anxiety appears in many forms.
Whenever it comes on, whatever it is called, it is fear. It may seem ridiculous that a person cannot even walk to the end of his road but that is the power of fear. It may be out of proportion but it is paralysing. It doesn't have to be forever. Anxiety in all forms can be treated.
