A panic attack is an abrupt surge of fear or acute discomfort. It includes severe physical symptoms that escalate very quickly (usually within a few minutes).
Illness anxiety (formerly known as hypochondriasis and health anxiety) is a preoccupation with having or getting a serious disorder despite having no symptoms or only benign symptoms.

Social anxiety (also known as Social Phobia) is a misunderstood condition. People often confuse it with being introverted or shy. But introverts are not by definition socially anxious. A person can be perfectly comfortable around people but may not enjoy loud gatherings. While extroverts feel energized after crowded get-togethers, introverts feel depleted and need to recuperate. Introverts, therefore, prefer solitary activities, but do not suffer from social anxiety. They may stay home on a Friday night feeling perfectly content.
