I clearly don't age.
But to the point.
I sadly haven't lost any control, but my bladder capacity before I get the urge to pee is tiny during the day.
It actually start to "hurt" if I try to hold it, so I either wear diaper, or use the toilet every hour or so.
Before I could soak the diaper with a full bladder, now it barely makes a dent.
Morning pee isn't any bigger either.
If i may be so bold. I had a therapist (who has moved to Sweden- so no longer available). That moved from traditional therapy to a Somatic therapy practice(look it up). While it was not regression therapy, we worked on mindfulness and learning to listen to the body. There was some therapeutic touch involved to help settle my anxiety. While it was not addressed as regression, i went there in my mind a bit. So it was helpful. Just my 2 cents. And yes she knew about my diapers. All of my therapists have.
