Symptoms of an anxiety attack can include a feeling of overwhelming fear, going crazy or losing control, or like being in grave danger or that you might pass out.
Anxiety attacks can include a surge of doom and gloom, an urgent need to escape, dizziness, or feeling detached from reality.
Physical symptoms can include heart palpitations, trembling, sweating, shortness of breath, chest pressure or pain, turning pale, feeling weak in the knees, burning skin sensation, pins and needles, hot and cold flushes, and numbness and tingling sensations. These can be accompanied by a choking sensation, a closing throat, confusion, feeling detached from reality or in a dreamlike state, emotional distress or upset, an inability to calm yourself down, a knot in the stomach, nausea, a panicky feeling, a pounding or racing heart, butterflies in the stomach, a sudden urge to go to the bathroom, vomiting, and feeling like crying. This is not even an exhaustive list. There are many physical, psychological, and emotional signs and symptoms of anxiety attacks.
Because each body is somewhat chemically unique, anxiety attacks can vary from person to person in type or kind, number, intensity, duration, and frequency.
