Stress has a cause and fades with it; an anxiety disorder persists, grows out of proportion, and starts interfering with daily life.
NIMH describes the pattern: symptoms that disrupt job performance, schoolwork, and relationships, with avoidance of ordinary situations in severe cases. The tells are persistence after the trigger passes, worry out of proportion, physical symptoms without clear cause, and a sense the worry runs you.
What to do
Common questions
How do I know if I have anxiety or just stress?
The line is persistence and proportion. Stress is a response to a real pressure - a deadline, a bill, a conflict - and it eases when the pressure resolves. An anxiety disorder is worry that persists after the trigger passes, grows out of proportion to the situation, and starts interfering with daily life: job performance, schoolwork, relationships, sleep. NIMH describes people with severe anxiety avoiding social encounters or feeling intense fear in ordinary situations - that avoidance pattern is a hallmark. Other tells: physical symptoms like a racing heart, tension, and stomach trouble without a clear cause, and a sense that the worry runs you rather than the other way around. A clinician makes the actual call, and treatment - therapy, medication, or both - works well.
