Why Do I Feel so anxious?

Anxiety is your brain trying to protect you - but sometimes the alarm system fires too often or too loudly. Understanding why helps you respond instead of react.

Evidence-informed content reviewed for accuracy and safety

Possible Causes

Overactive threat detection

Your amygdala can get stuck on high alert after prolonged stress, scanning for danger that is not there.

Caffeine and stimulants

Caffeine blocks adenosine and raises adrenaline, mimicking the physical sensations of anxiety.

Uncertainty and lack of control

The brain treats ambiguity as a threat. Major life transitions or unpredictability spike anxiety.

Physical vs Emotional

Physical anxiety shows up as racing heart, sweating, and muscle tension. Emotional anxiety is the constant mental loop of worry and worst-case thinking.

Self-Check: Ask Yourself

  • 1. Is my heart racing or are my muscles tense right now?
  • 2. Am I worrying about something specific or is it a general unease?
  • 3. How much caffeine, sugar, or alcohol have I had today?

What You Can Do

Try box breathing: inhale 4 counts, hold 4, exhale 4, hold 4

Name 5 things you can see, 4 you can touch, 3 you hear (grounding)
