The anxiety attack I had some ten years ago (80 now) that choked my breath so that I jumped out of my bed before dawn turned out to be the result of something I was fretting about 'too much' though in hindsight I still believe it was 'worth' feeling that bad -- I suddenly found the four full-time years of seven days a week on my 'labor of love' writing work is what no book agent seems to be interested in.
When I asked what assurance I've that I won't have it tonight, I was offered 'we can watch you if u wish.' Of course I slept well, confident that help wud be instantly provided. I was offered CBT. I said I know that; I can do it myself. Thinking CLEARLY we all can, and do, as we GROW UP. I grew up when I accepted that in this world, EVEN when we work HARD, the results may not be what YOU Expect. If I do not accept or even willing to 'know' that this is what happens in LIFE then I AM DOOMED.
I hope my story helps you find some way out of your anxiety -- before it saps more health and joy away from your body and mind -- and the health you still have.
(Often I get my kick-to-live when I hear news such as the Pussy Riots leader when asked, 'don't you worry about your getting imprisoned,' she said, "I don't have time for that." The interviewer had to repeat her answer to be sure. That's a woman I get a jolt of energy to Live on -- even as I feel the demands of the old age.) But now (11 pm) I'll get from an hour of classical music on radio; I do hope you will get yours.
P.S. Didn't you notice in your answer to the water in the glass you Are Already Half the Way There?
I just have to respond to the Pussy Riot mention! My daughter took me to hear them lecture some years ago at a local college. The audience had light weight artistic career worries--are you afraid to sell out? But these women, living under such an oppressive regime, basically said the same thing--we don't have time to worry about that. I think that is what it means to be a heroine/hero--inspires me too.
