Gman,
Thanks for starting this thread. There's so much to go with - great responses from imperfection, and the usual scholarly discourse from TC (TC do you have these thick reading glasses, swirling cigar smoke and an old puffy leather chair in your study with parchment tomes on ancient bookcases? I just have this vision).
I was diagnosed in the past with mild OCD (thoughts) and anxiety so I relate to a lot of what you said. I also used to have a constantly churning gut, and deep unease and disquiet.
All these things have disappeared. I firmly believe that it is because of hisboidedus.
I wish I could, but I can't explain how. And the more I try to explain the more likely I will be steering you away from the real ways hisboidedus works.
However, I will try my very POOR best to give my sense of what I believe was going on with ME - and it may just be that it applies to you too.
I posit that your neshama is in great pain: it's trapped possibly by the mediocrity of all your deeds. If you are incredulous at the suggestion, ask yourself: how good is your shachris? How good do you think it is to be close to Gd? Are spiritual endeavours something so dear and precious to you? If you can't answer a strong yes to these, then it's possible your neshama is in pain and the symptoms you report are manifestations thereof.
Hisboidedus has this unique ability to lift up all your actions, that you aspire to better things - and it addresses the deficiencies mentioned in the previous paragraph. Of course it does so much more, and there's other ways hisboidedus works that I can't articulate.
What is hisboidedus: making time when you talk to Gd in your own words undisturbed by people or things, and with no pressure to rush your words. These are things that so few of us find in the regular davening (we've got to get to yishtabach, no?) and this used to be how klal Yisroel davened before anshei kenesses hagedola were koiveia the nusach hatefilla. It's the way of the avos, Dovid hamelech - and so many others.
With it is sweetness, deep peace, security, and trust.
To give you an idea: I used to be a swimming junkie - clocking up miles four times a week most of them 7am in the pool - and it gave me a lift all day - as we all know it does.
I reduced my swimming as hisboidedus took its early morning place. And if it didn't give me more chiyus, life and peace I wouldn't be doing it.
I suggest that it is worth giving it a try, because with time it can relieve you from some of your symptoms. And if not.., have you lost...?
POST-SCRIPT: I may get flak for 'unscientific hocus pocus' and for the presumptions I've made. However I can tell you that I was one sick bunny and I am a different creation because of hisboidedus. I'm saying what worked wonders for me.
I'm not advocating not seeking medical attention particularly where it causes severe distress and life has become unmanageable. I recognise that Gman may not have what I had. Nevertheless I believe in what I've advocated. Also for a number of reasons I haven't quoted sources to support what I advocate but this is not completely my own notion.
PSS. Gman, Could you not decide how to spell anxiety?
