Hey, GS... I'm a bit more centered this morning and will try explaining better, my experience with all this. But first - I wanted to make clear that I think what you're doing is absolutely the right thing... it will work. And I think I'm a very real person in 3-D!

I heard you loud & clear!
A couple things worked for me, to occupy the L-brain chatter long enough, completely enough, to get glimpses of the r-brain awareness - my r-brained, happy - "it's all good" - self. One is simply sitting outside, and watching the birds I feed (and the rest of the outdoor menagerie) play. Pretty, bright yellow goldfinches know that I supply lots of thistle and bird seed. The wood peckers know I hang up suet & seed blocks for them. And the robins and squirrels and bunnies all come very, very close to "visit" me in the mornings... they know I won't hurt them or scare them. I just let myself watch and enjoy them. It feels good.
Tai Chi also worked, because L-brain had to remember the order of 103 different moves - some of which are repeated at different points. Each of the 5 sections of the long form, have a different order. It's hilarious to me, that I learned to memorize this order so well... and L-brain was so obsessed with the memorization... that it was during a ranking test performance, that I got my first glimpse of intense R-brain self and that awareness so freaked me out that I completely botched the order!

Yes, there was a painful memory - I saw Lbrain jump up & down in evil, abusive glee in my mind - saying "See? I TOLD you... you can't do anything right... you ALWAYS screw things up!" R-brain experience - that feel good, centered, place - was considered "dangerous" and a serious breach of the "rules".... bad. According to L-brain.
It took me a year of thinking about this... looking at it... and the book Stroke of Insight... to finally understand that experience. For me: L-brain is the home of ego. And it's Ego that feels pain. Ego, for me, is the one screaming I AM IMPORTANT TOO. But the kind of emotional abuse we've endured in repeated, constant streams... somehow perverted my ego into becoming the abuser - I guess, as a defense mechanism gone mad... so that I would put myself down, internally heading off, hoping to divert the expected worse abuse... and continued long enough to become a habit, to disallow r-brained well-being. [edit: OK, OK, tortured syntax.... it's still an accurate description]
The last thing that worked for me, was the computer game Bejeweled. There was just enough to "do" for left-brain - trying to match colors & shapes - that left-brain's "guardian of the gates" attention wavered... and up would come all kinds of unrelated bits & pieces of r-brained memory. I just let them come... most of the time there wasn't even a thread of a sentence or thought. It was sensation memories... little tiny chunks of the past. Of me...
I didn't have to do anything with them. Just say: oh, I see - hear - remember that. Acknowledge it. Let it come up and file itself away into the "puzzle" of me... playing this game became a structured way to take a "r-brain break"... to stroke and soothe r-brain... and to disable L-brain's egotistical, abusive control over r-brained experience. It couldn't do 2 things at once!
So when I started putting all this together, I began to see that I was my own worst enemy. L-brain's "Guardian of the Gates" mentality was the problem. It's fear of r-brained experience was unfounded; unjustified. It didn't have to keep on beating me up for my "R-brained moments" that, like "senior moments" seem unproductive, silly, or just fun... just being or feeling FINE. Heck, that r-brained stuff is ME TOO. And L-brain has nothing to fear from it... it's not a threat to L-brain's "Git R Done" processes or self-important needs...
So I started practicing being both at the same time. First in tai chi... then, little by little, in other things I do. It's very easy for me to shift my center of gravity more to the left or right - as the situation warrants - though moving right takes a bit more attention to "letting go". And I'm still practicing - a LOT. There isn't any "right" combination... or any "ka-chunk" knowing when it's the "right" balance... it's ALL "right"... wherever I am at that moment.
My L-brain has a tendency to think that I have to meet some specific criteria all the time, to be acceptable. It's WRONG. Just flat out wrong. That idea is stupid - and you can't fix stupid. Stupid isn't "bad" or shameful... it's human and I have to accept and allow myself those moments TOO. Like the times I find myself putting a hot coffee pot in the fridge... duh!

(too r-brained moment)
But IT'S OK THAT I DO THINGS LIKE THAT, now. It's OK, if I still need to vacuum or haven't brushed the dog... I did other things that needed to get done - or I just had FUN... so it's OK. There simply isn't any real "waste of time" - not even spending hours watching the birdies.
And I think that overall, I've become more "functional" with this practice. I'm much less reactive (tho' my mom is still a problem area). And I'm seeing that those "weak" points that I'd beat myself up about, are one side of an equation. On the other side, is a NEED. If I address the need... (become my own "good" mom to myself)... then L-brain's nasty comments don't have any basis... and it shuts up.
PHEW... OK... that's a lot of babble about me and what I've been doing. Maybe sharing this, you'll find something useful; maybe not. Like I started out... I think you're on the right path and you'll start seeing the same kinds of things very soon. There is peace and RELIEF and COMFORT there... and I'm sure you're going to find it very soon.
XOXOXO (((((((((((GS))))))))))))
