Hi Halcyon. You could try the 4-7-8 breathing exercise.
- Find somewhere comfortable to sit and if you can close your eyes.
- Breathe in through your nose to the count of four.
- Hold the breath to the count of seven.
- Exhale through your mouth to the count of eight.
Concentrate hard on the counting and don't allow your thoughts to wander.
It's quite a well used exercise for anxiety and panic attacks, it can also help if you're finding it difficult to sleep.
The exercise did work for my son who was going through a very difficult time. It probably won't stop the attacks happening but it could give you control of how much they effect you and give you a chance to start to control them before they get so scary. <<<hugs>>> Jo.
