Hey AIC, the only other thing that I can think of that might help, may not be any help at all, in which case please feel free to ignore me;)
I realized with my health anxiety, and anxiety of things that felt out of my control, that it was all indeed, control-centered. I am uneasy about
most things that I can't directly affect by my own will. For instance, I can do a ropes course 100 ft up in the trees. I can walk the shaking ladders, tight ropes, and switch carabiner connections like a champion...but the free-fall zip line? Uh-uh, no-no! Nearly lost all bodily functions on that part, because I had absoluetly no control at that point.
There came a part of my recovery that I discovered that I needed to get over this issue to some degree, if I was to get better. I started to repeat to myself things like "What if I become sick, faint, whatever? I can't change anything by worrying or not worrying about
it"
I also used this when I was flying. I repeated the mantra "I can't control anything but my own thinking, and I am going to choose to let go of this worry." I realized that whatever was going to happen was going to happen whether I was stressing about
it or not...so I choose not! It was strangely freeing. Was I still nervous with the pit of my stomach sensation upon take off and landing? Sure, I mean I was still in a plane after all, but it was manageable.
This may, like I said, make you feel better, or worse...I hope better, but I know this way of thinking is not going to work for everyone, so do with it what you will:)
Take care,
S.C.
