I think I understand, I'll share something similar that happened to me after I recognised I was Autistic, in the hope it might be of help.My anxiety seems to be able to squash every good intention these days.
Just the thought of having to leave my house is enough to make me tremble like "green saplings in a breeze".
The only times I can detach now, are when reading an easy book (good fiction, no factual stuff), doing crafts, fiddling with my machines, watching a video, or playing a game.
Absolutely anything that makes me think about real life, causes my anxiety to go up.
The new awareness brought a different type of anxiety, coming ftom the permanency of the areas I struggled with.
Eg I'm anxious because the threats I could face are real, I actually can't navigate certain social situations, it was bigger than this example, spanning all areas of my life, kind of like an existential crisis.
Regulating my sensory sensitivites was a building block for handling anxiety inducing situations, the two for me are interconnected.
Anxiety is a continuous companion in life, Im always working with it, most times though it respects the boundaries Ive given it.
I guess whst Im saying is that while anxiety can be managed this requires a lot of work.
