I feel the claustrophobia... Anything blocking my nose or too tight on my face makes me panic. It sometimes gets so bad that even tight hugs or snuggling with my SO will set me into a panic because their arm is too close to my face, or the fabric of their clothes are covering me. I found out I had this sort of reaction when I went snorkeling once... and also, now I have a CPAP that I'm supposed to wear but nope, can't get used to it, no matter how many times I try the smallest form of face mask, just can't do it.
