Just out of curiosity, what is the difference between "hearing voices" In your head and "intrusive thoughts"? I don't really understand how you could hear voices in your head that aren't your own thoughts. Surely if you hear a voice in your head that says you're worthless for example, it's the low self esteem part of you that's given you those thoughts and not a delusion.

I'm not denying it happens, but i'm trying to understand how its different from your own thoughts/talking to yourself (I heard talking to yourself is actually very normal and shows intelligence.)
