I'm not too great with words at the moment, but will try. I entirely relate to what you're experiencing.....unfortunately. Things had been progressing in therapy for me and I was working on more and more things lately - rather all over the map tbh! Now I'm in this situation like you are with body memories, and constant tangled, twisted.....you know, you're in it too.
Also the situation you've had with things that used to soothe but now there's connections everywhere? Yup. It's not perfect, but I keep trying. I fall on my face, crawl, stand up, try something else. I guess, I hope eventually it will work. You haven't gotten this far along your journey without incredible strength. I think we lose sight on that fact so easily. What we used to do to compartmentalize, ignore, lock away our selves & emotions took tremendous strength to hold. It felt controlled and manageable, this now doesn't. But it's a road we're building inch by inch, we have to clear it before we can make a smooth surface. Sometimes our tools go missing, or we misplace them, so we have to go back to old tools that might not work as well, may not be healthiest....but they get us through until we can relocate the ones that work better.
This next bit I was gonna write in my diary, but thought maybe it could help someone else as well.....
With this whole Covid19 situation - there's a sense of not knowing when it will get better/end
My current body memories/brain noise has that in it too - not knowing when it would stop/if stop would be dead
I dunno....maybe it makes sense to you
