Its great that you're aware and willing to admit to low PMA, and that you're trying different ways to boost it up.
Noting that your Mom's actions were triggering anxiety in you is big. I think most people bring their family's ghosts with them into M, with a similar behavior by a spouse leading to similar anxiety, for example, and perhaps being misread by the spouse, and so on...
Knowing that it happens, then nipping it in the bud, will help in a future R. I'm trying to do the same thing when I notice it in my interactions.
