Mindfulness can be an effective way to deal with anxiety and panic attacks.

1. Investigate your thoughts and ask yourself “Is it really true?” Remembering that your thoughts ain’t facts.
The thoughts will often be about the future, so ssk yourself “Am I OK right now?” Moving your focus back to the present moment and away from the minds fear based catastrophe scenario. You can take a sober look at the future when you feel more balanced).
2. Breath. Slow deep breaths. It helps regulate the nervous system and it gives you something physical to focus on rather than the mind loops.
3. Use your senses. Listen to sounds, watch colors and reflections of light, smell the air, feel the sense of warmth and cold. Try to do it without naming the experiences. Just experience them “raw”, as they are.
