Welcome to PC. Know that your friends are getting the best care they can. Try to breathe slowly. I understand you are scared and phobias are hard to deal with, but hang in there. I used to have panic attacks so I'm sure you are having similar reactions. I conqured them with pacticed breathing. Count 10 as you breath in and count to 10 as you breath out. continue until you feel calmer.
Wishing you and you friends the best.
