All wonderful replies, IHMO:) To me, exercise is crucial and vital to our, overall, healing paths from anxiety / panic disorder(s). It needs to be a part of the program for all of us...there just isn't any other way to look at it, to me:)
Pushing through fears can be troubling, for sure. But, pushing though fears is, inevitably, needed to find our way back to some peace:) I know how mountainous challenges can seem when we are amped up with fear, panic, anxiety and insecurities. These dominate fears are driven by our anxiety issues...the true outcome of situations is rarely, rarely, rarely, rarely as bad as we have built it up in our weary minds. We don't die - nobody dies from anxiety / panic, though I know how we feel that we are destined to be 'short-timers' here on Earth, sometimes.
All we can do is get some focus (as best as we can) and try. If we stumble a bit and, maybe, "fall-down", we can get back up, dust ourselves off and try again. And repeat. The trying does get better, eventually:)
There is always help and hope. Always!:)
Peace and Feel Well:)
