I'm sorry you are experiencing this. It's happening to me too. Not delusions though, mine are real. It's because I'm filing a lawsuit against "the men in charge". My inlaws are in on it and my "best friend" might be too.

I want to die on my own terms, not be murdered to silence me and steal my diseased organs.

Touch some walls and see if it goes away. My family said to stay in my house, near my dogs. Do you have people who live with you, who can support you through this?
