Sorry you're going through so much! I just wanted to say "hi" and maybe give some hope. What's happening with me is that it is loud, still, but it is so pervasive that it's becoming like background noise. I forget about it at times. I remind myself that it's not actually harming me in any way. Focusing on other things helps, too. Deep breathing, alternate nostril breathing (sounds weird, and it looks weird, but it seems to dial down the angst t can create) are all different interventions that can be done and be effective. I don't have all the answers, and, as you know, have some other physical things going on, etc. But, for the time being - and it does change throughout the day, so not completely out of the woods - things are better.
Please take care of yourself, and I hope you get some relief very soon.
