# Understanding the Anxiety Spectrum: From Normal Worry to Clinical Disorder

## Quick Summary

Anxiety isn't a light switch — it's a dimmer. Everyone experiences worry, but anxiety disorders occur when that dial gets stuck on high. The GAD-7 screening tool measures four distinct levels: minimal (0–4), mild (5–9), moderate (10–14), and severe (15–21). Understanding where you fall on this spectrum — and what each level actually means — is the first step toward knowing whether what you're feeling is a normal response to life or a signal that your brain's alarm system needs recalibration.
