Anxiety & panic

A racing heart, tight chest, and a feeling that something is seriously wrong are common during withdrawal — and genuinely frightening, especially with brain fog making it hard to think clearly. You're not overreacting.

What panic can feel like

Pounding or racing heart, tight chest, shortness of breath, shakiness, sweating, a wave of dread, or a feeling of being outside your own body. It usually peaks within about 10 minutes and eases from there, even though it can feel endless while it's happening.

Grounding techniques that can help in the moment

• Slow the exhale. Breathe in for 4 counts, out for 6 — a longer exhale than inhale signals your body to calm down.
• 5-4-3-2-1. Name 5 things you can see, 4 you can touch, 3 you can hear, 2 you can smell, 1 you can taste. Pulls attention out of the spiral and into the room.
• Cold water on your face or hands. A genuine physiological reset, not just a distraction.
• Say what's happening out loud or in a post. "This is panic, it will pass" — naming it reduces its grip.

Why this happens during withdrawal

Your nervous system is recalibrating, and that can show up as anxiety or panic even in people with no prior history of it. It tends to ease as physical withdrawal eases, though for some people anxiety lingers longer than the physical symptoms do — see Mental health & cravings for more on that stretch.

When to involve a professional

If panic is frequent, severe, or not easing over time, that's worth bringing to a doctor or therapist — see When to seek professional help.
