Aaa that sounds absolutely terrifying I’m so sorry you’re dealing with this
Personally what helped me was wrapping so many blankets/pillows/stuffed animals around me that I could barely see and hear, also a consistent sound (I shake my leg but you can do other things like maybe soft noise on earbuds) to keep from noticing every shift of the house
Hope this helps<3 if you ever need any advice, help, or just to vent I’m always open!!!!>!!!
