If you are having anxiety and/or panic attacks, the best
thing you can do for yourself is to practice this method:
1.Relax.
2. Count to ten.
3. Breathe.
It doesn't matter whether you count forwards or backwards. Both are fine. In fact, you can alternate, if you want.
But, when you breathe, do it as softly as you can--and be mindful of each and every breath.

Best of health & good luck.
