Hi @Anastasia
I'm sorry to hear that your boy is going through this.
I also hear voices... they're always frightening and disturbing. Instead of looking at the voices I hear as a scary symptom with no meaning, I try to view the voices as trying to tell me something. For instance, they could be trying to tell me that i'm anxious or lacking in confidence. This really helps me with managing the voices and living with them. It even makes them less intense alongside taking my medication, because I'm not constantly fighting with them. I hope this is helpful.
Sending strength to you and your boy.
