I was 28 when I heard "voices". My initial diagnosis was schizophrenia then it changed to schizoaffective with bipolar. I was very stressed out when I heard them. They suddenly appeared in my head. I take Abilify now for this and mania. I have paranoia and delusions with my voices. However, over the years my paranoia and delusions have waned but the voices remained which is the reason for taking Abilify.
