I use breathing techniques to help me through. Here is the one I use. It takes practice so you have to practice when you are not having one so you will be ready when you do.
Take a deep breath in through your nose to the count of 4.
Hold your breath to the count of 7.
Exhale through your mouth to the count of 8.
I do this 10 times to relieve anxiety symptoms. It takes practice.
