Like fear, anxiety is a perception of an aversive possibility or threat to something we care about and a consequent desire to avoid it. But in the case of anxiety, the likelihood of the threat coming to pass is less clear, specific, or definite. For this reason, what can be done to avoid it is also less clear, and while the desire to do so is therefore less urgent, the emotion can be marked by a debilitating sense of helplessness.
