Hi Bettyanne--
I think the things Tupp and Amber (Skep) have said here are poignant, practical and empowering.
I'm no expert on codependency. Back when I read the Melody Beatty books about it (have you had a chance to?) my problems with co-D were all about my relationships with men. Relationships still pose similar challenges for me. (If anything, though, I've overcompensated for codependency with ferocious boundaries at times.)
When a negative mother has affected someone as powerfully as yours has, reclaiming or rediscovering your self, as Amber mentions, sounds like the most satisfying and important job of this chapter of your life.
How can you rediscover or reconnect with the actual person, Bettyanne, who isn't just a symptom of her mother? You are so much more than that. It may be a slog, but I just keep thinking of very simple things to complement your psychotherapy.
They'd be on one level distractions from the nonstop rumination about your mother. On another level, they'd tap into a part of your mind -- creativity -- that belongs to every human being. You could find perhaps that in trying one or more of such things, your mind would get focused on an activity itself, and that concentration might give the other parts of your mind a rest from re-living life with your mother.
It might sound too simple, but what's to lose?
Some form of art--anything. Is there painting or pottery or drawing or sewing or embroidery or craft or growing (starting seeds indoors to plant or give away) or anything remotely like that (I loooove finger-painting) that appeals to you?
Some form of music--anything. Would a harmonica or harmonium or autoharp or keyboard bring you pleasure? (Like the pleasure of a little kid left alone in a room with something that makes good sound -- NOT like the pleasure of an adult who feels obligated to do it right or impress anybody else).
[AFTER pandemic.] Some form of theater--anything. Is there a children's theater or local troupe you could be a supporter for? If you don't perform, they always need props and costumes and backdrops or rehearsal snacks. It's just fun to be around.
Lastly, the best thing I know about is what Amber mentioned--getting your mind off your own sorrow by responding to another's. That's really challenging right now for older people, how to volunteer safely during a pandemic. So maybe it'd be making baby blankets at home, or calling shut ins, or something similar for now. But once you're safely vaccinated, volunteering in some simple but satisfying way might be a great thing to build into your life. (Volunteering for a telephone tree is perfect now.)
I once interviewed Alan Luks, who founded the Boys and Girls' Clubs of America, about his book on the scientific research on altruism. (The Healing Power of Doing Good). The most powerful finding to me was that scientists all had discovered that health measures actually changed in reponse to doing altruism (such as BP, illness, energy, longevity, even cholesterol!). The distinction I found most remarkable was that all altruism benefits both giver and receiver BUT with this difference:
1) donating a check, dropping off canned food is good for your health
2) handing a needy person money or feeding them a meal and joining them is great for your health
Those are just examples but all such interests can be put through the same filter. Giving money to the children's hospital is good for you. Having a regular shift rocking babies in the NICU is great for you (one of my future volunteer fantasies).
I know most of this can't kick in until after we're vaccinated. But maybe the creative stuff could help heal your mind right now without waiting. It might be about PLAY. The powerful healing and joy-making effects of play. Because with a childhood and adulthood that didn't invite you to play....now might be a time to find out what that feels like.
(You're also grieving, so play might not be giggly-happy. But you can weep while using watercolors. It'd be so great if you found something-anything like that that connects with your inner spirit that has always belonged to you.)
Hope this helps, or a word or two of it.
hugs,
Hops
