Stress vs. Anxiety: Understanding the Key Differences
Stress is a response to an external trigger and typically resolves when the situation changes. Anxiety persists even without a clear stressor and involves excessive worry about future events. Both activate the fight-or-flight response but differ in duration and proportionality.

Professional Diagnosis
Stress is a normal response and not a clinical diagnosis. Anxiety disorders are diagnosed when symptoms persist for 6+ months and significantly impair functioning, per DSM-5 criteria.
Treatment for Stress
Time management, exercise, adequate sleep, boundary setting, and relaxation techniques.
Treatment for Anxiety
CBT, SSRIs or SNRIs, mindfulness-based therapies, and lifestyle modifications.
When to See a Doctor
Seek help if worry feels uncontrollable, interferes with work or relationships, or causes persistent physical symptoms like chest tightness or GI distress.
