The breathing issues were very overwhelming to me initially (uncertainty in understanding, knowing wat it meant, etc). Couple things have helped me...i purchased an pulse oximeter to see if i could identify any patterns, correlations with oxygen levels (i have times when low and avoid things that cause it to be low). Another thing was that i never knew how i would know if i actually was having problem but seems i am ok if i can take breathe then count out loud to 20...if less than i know to take it easy
