Anxiety voices? Like intrusive thoughts? Yeah, I've had those. Still get them sometimes. They're not nice, to say the least. My therapist told me to argue back with them, and imagine a more reassuring voice speaking to me, arguing against them.

Or do you mean actually psychotic voices? Had those as well, started to believe that those voices were other peoples thoughts. They were pretty scary.

Whatever kind of voices they are, they're never nice, and I hope you get some peace from them soon, my friend.
