Fear is seen as a reaction to a specific, observable danger, while anxiety is seen as a diffuse, a kind of unfocused, object-less, future-oriented feeling or foreboding. Worry about dying is more likely to take the form of nagging anxiety than a specific fear of dying in a particular way. Anxiety has diverse forms linked to an array of emotional states such as doubt, boredom, mental conflict, shyness, stress, disappointment, bashfulness, self-abasement. This diverse array can set you up for fears. The goal of therapy is to reduce anxiety, not eliminate it. See https://www.psychologytoday.com/au/blog/science-choice/201812/anxiety-vs-fear
