Thank you both for your answers, I'm sorry I couldn't thank you sooner but I was on a psych ward.
Has anything worked in the past in terms of helping to get them to stop?
Music used to help, but now it doesn't do anything anymore.
Have you tried challenging them, and speaking outloud to them to tell them to go away, and that what they say is not true, and that they do not have power over you.
I've tried several of those, but it just ended up with them screaming in my head.
