Breathe: Panic attacks are a result of a buildup of CO2 in your blood brought on by holding your breath when stressed. Take a deep breath, hold it for a count of ten, keep doing this until your blood ph is normal, i.e., when you feel better. Also, talk to yourself, aloud if you are alone, and tell yourself everything is ok, you are ok. Works for me, plus I take meds (Prozac)
