Fun fact about panic attacks. One of the physical symptoms is the inability to catch your breath. What that tends to mean is you are breathing in too much, but not out enough, raising the amount of O2 to your blood to dangerous levels. If you can't manage breath control, breathing into a paper bag helps because you're re-breathing lots of CO2. As an added bonus, helping the physical symptoms of things like panic attacks also help alleviate the psychological symptoms. Fun facts from me to you.
