I know you've done the entire SEP, which is awesome - but a lifetime of anxiety is not easy to overcome. Have you considered therapy? Or a program (perhaps not here) that is aimed specifically at anxiety?
If you found a TMS therapist, they accept that anxiety is actually a TMS symptom and can gear therapy accordingly. The insidious thing about anxiety is the vicious cycle of TMS creating physical symptoms which create more anxiety which creates more physical symptoms, etc etc etc. And it's "inheritable", meaning that it runs in families. I know without a doubt that my mother gave me anxiety during her pregnancy (she had way more equanimity with my three younger siblings) which took me years to figure out by piecing together bits of information - confirmed in her last years when her anxiety resurfaced with a vengeance.
So I was always an anxious kid, even though I had quite a secure and loving upbringing (apart from too many siblings!) I had sixty years of anxiety before I discovered Dr. Sarno in 2011 - it was a challenging hurdle that has become even harder due to societal dysfunction in the last, oh, let's say six years - compounded by the trash dump brought on by the pandemic, climate change, and now the threat of world war.
What's not to be anxious about? I've been in therapy with a TMS-trained person (who is a LCSW in her state, but not mine, so legally she is my "coach") since the summer of 2020 (every other week for quite a while now) and the equanimity she provides is invaluable. That's her favorite word, in fact - and one which I want to remember to use and incorporate much more than I do.
