I suffer from GAD too, it's a beast. Medium is like you described, pure therapy. I'm not yet 40, still have 5 years to go, but I feel the same way about my poor heart and achy muscles. I'm in pain and I sometimes forget to breathe. It's gotten so severe at some point that I was seriously thinking of changing careers....talk about pre-midlife crisis. Thanks for talking about this, the world needs it.
