My cat who always sleeps on my bed, my blankets, having some kind of soft background noise like music on quietly, and now my meds all help. When I've had really bad times, having a knife under my pillow, sleeping on the couch so my back is to the wall and I could see the whole room, and having my shoes and car keys by my bed so if I had to escape from the house, I could do it in a hurry - those all helped me. It was all in response to fear over previously being stalked and threatened. I still sometimes like to have the keys by my bed but it's not as bad anymore. I hope things get better for you.
