People who feel anxious often show some physical symptoms that are easy for a person to identify, while others are more difficult for a person to recognize visually. For example, a person may feel restless, have a choking sensation, increased heart rate, chest pain, nausea, dizziness, hot flashes or chills, and numbness that people are unable to notice unless the person with these symptoms don't explain what's happening. A person would be able to see someone who is feeling anxious start shaking, breathing heavily, or having sweaty palms. People who feel anxious will also show behavioral differences. For example, they will start avoiding situations, trying to leave situations in which they feel anxious, becoming self-destructive, limiting themselves and attaching themselves to objects and people. People who engage in these types of behaviors usually deal with feeling anxious or try to avoid feeling anxious at first. Anxiety can also change cognitive thinking processes, leading them to question various aspects of their life, even if it has no direct effect on them, or if the effect does not occur for a while. Anxious people have difficulty dealing with the unknown, often feel like they are going crazy and feel trapped. It is important to identify these behaviors and physical symptoms in yourself and others to avoid a potentially dangerous situation and prevent your anxiety from becoming uncontrollable or to ask someone for help if it is already becoming too much.
