Distracting the mind helped me. I realised if I could get my mind not just to focus on something else but be consumed by it, it would leave little room for anxiety. The trick is finding
something that works for you. Here's 2 examples.
Travel & Holidays. During the time I was having panic attacks, we had a holiday booked, so off we flew to Barcelona. In just 2 hours from the UK you
arrive in a country with a completely different culture, climate and cuisine. Being absorbed with the delights of this Catalan city proved to be a real distraction for me and a great tonic. Wherever I turned there was something of interest to see and enjoy. Warm sunny weather; amazing food; unusual architecture; sea air; boat trips.
So good we went back the following year.
The 3's Game. The idea is to find a quiet place and simply think of 3 things you can see; 3 that you can hear; And 3 that you can touch. But really try to look and listen. Take time and don't rush it. And as for the items you can touch - well touch them.
Just a simple game again to try and trick the mind to switch off from anxiety by focussing on something else.
