To start finishing up this whole area of topic...
I decided that it simply doesn't matter if I am persuaded that our brains generate the chemicals that we are aware of through our body... and that this is ALL emotions are. I can still work with this as a provisional premise, even if I'm not totally convinced of this. Somehow, I still "feel" that emotions are a little more than this combination of thoughts/chemicals experienced physically in a feedback loop... but I can accept for instance, that meditation or tai chi can activate and condition the parasympathetic nervous system and enough experience of this can counteract chronic runaway thoughts or anxiety. Or that addiction itself is a feedback loop, involving dopamine and other chemicals that "feeds" the body what it thinks it wants/needs.
So... that begs the question of whether the body itself has intelligence, or if it simply has a 1/0 perception - on/off, feels good/bad - like some bio-switch. Is it the body that sends out an immune response to heal a scratch? Or is it the brain? Or is the brain part of the body... and if so who's in charge? The book I read also proposes that some magical chemical combination of brain and body creates the "mind"... and supposedly the "mind" is in charge, in a smoothly functioning system (i.e., person). Ah... but then things get too complicated... with the automatic brain processes related to body (like breathing)... and unconscious, subconscious... and what we normally call "consciousness" - which is still subject to the telescope like lens of perception and attention-focus.
If I haven't lost ya yet, what occurred to me... in trying to "translate" or create a dictionary of understandings between our emotional language and this neuroscience approach... is that in my own case, I've let my body dictate to my brain what my habits will be. It goes against everything I rationally know to smoke, I've lost people whom I really cared about, because of smoking. I tried to find some emotional "key" to unlock whatever un- or subconscious process would let me gain control over that habit. But I should've been looking for that emotional key in the body, rather than my mind.
THIS is still total conjecture/theory/guessing on my part... but what I think is going on, is that I'm highly aware of my body states... and by fixing my attention on how my body feels... I'm actually letting it decide or choose what I do - whether it's good for me or not. How I became so aware is probably a combination of DNA, and the turning inward of attention via the environment of invalidation soup that I experienced in my FOO, and perhaps also my unique reaction to the high level of shame I felt - some of which, really wasn't mine even though it was tossed in my direction and "pinned" on me.
The flip side of that body-awareness is psychosomatic symptoms, for me. Particularly, stress-related. Particularly, anything emotional or a conflict... anything involving my mother or brother... and also my new "role" of business owner, because it's finally my job to make the choices and decisions instead of being told what to do... and then trying to confront my own self and make these "habit changes" I want (intellectually). My body can raise such resistance and misery for me... that it seems to want to be in control of deciding and choosing... instead of respecting my mind's rational understanding, limits and desires. The body "mind" can even be pro-active and create panic, anxiety, physical pain and discomfort through muscles and skin eruptions to even keep me from starting or sticking with a plan of change. It can literally "fight" me... and seems to have a mind of it's own, though that's limited and doesn't have the neo-cortex's higher reasoning capability.
Just coming to this understanding or description of what I think is going on with me, is quite enough to send my body into overdrive to create pain and misery to stop me pursuing this path. My old shoulder injury flared up worse than I've experienced since I was 12; lots of nerve based referred pain, as well. I have an old friend who's a PT and her suggestion of ice (instead of heat) has helped. Then, I am going through a case of hives -- either that, or some insect has been making a huge meal of me, un-noticed (hardly likely). I had hives way back when, too... and was told that I was allergic to chocolate (not true)... it was most definitely a reaction to a specific kind of stress, involving serious change. The only other time I experienced this was for a month or so, when I graduated high school and was making plans to leave home and never return.
What brought all this on, is that I reversed a common strategy for smoking-cessation. My body-brain is programmed for more, more, more with absolutely no concept of "too much of a good thing". So the tracking of my smoking - recording each one that I smoked - actually backfired; it was like my body was trying to get a higher score! I've tried this maybe 10 times, with exactly the same results until I finally gave up. This time, what I'm doing is counting backwards - I'm writing down how many I choose to smoke today (always moving to lower numbers, gradually) - and then crossing off the highest number as I smoke one.
In effect, I rationally, consciously imposed a limit on the body's nicotine/dopamine appetite that it isn't smart enough to get control over or sabotage... so it's venting discomfort via the psychosomatic symptoms above. I didn't really anticipate this reaction; I was still working out the ideas about emotions - body chemicals - etc. But this whole theory make SO much sense to me, given that the ONLY time my mom paid attention to "how I felt"... was when I presented physical symptoms to her; at least, until the time I finally turned all that inward on myself -- and then her physical approach to my "discomfort" was completely inappropriate and only made my emotional distress even worse...
... and that paragraph above, reminds me of the movie inception: a dream within a dream within a dream - only it's multiple feedback loops instead... in different programming languages between my brain, emotions and body. I keep wondering if I might just be making myself nuts... trying to work through this by myself - with only hubs' feedback. But I don't think so.
It seems to me, given the specific physical ailments I'm experiencing, that I've struck a little too "close to home" - spot on even, with this new approach and some other things I'm working on simultaneously. It's too coincidental that it's exactly the same physical stuff I experienced in reaction to my mom's denial that I'd been raped, you know? And I've observed that with the counting down technique -- I pay attention to it once in the morning, so I'm not spending a lot time thinking about smoking - just crossing off this one... and just like the opposite process clicked into the more-more-more... this process, seems to leave a few not crossed off - and so not smoked - at the end of the day. With no typical withdrawal symptoms or cravings. Go figure.
The other association I can make with the idea that my body thinks it can make decisions; is in charge... is that this is exactly what my mom drummed into my head... this was her "technique" for dealing with emotions - all emotions. It's like she got the old wives' tale about fevers and colds all twisted up: feed a "feeling"... so it goes away, changes, you don't feel it anymore... more-more-more (because it doesn't work, you know?). And I've got a whole wagon-load of feelings about my mom - still - that it's friggin' pointless to express to her; that venting here hasn't removed, though they are less intense and importantin my daily activity... and I'm currently disobeying the mom-law of feeding those feelings some substance to make them disappear... so I think I need to do some intentional "letting go" via limiting my exposure to thoughts of those feelings - and my mom in general. Maybe that'll help with the physical symptoms... we'll see.
