A warm welcome to HealingWell. I am so glad to see you join this great forum.
I will just give you some info but I want you to please remember I am not a professional and you need to be evaluated by a physician.
Schizophrenia is a chronic, severe, and disabling brain disorder.
People with schizophrenia sometimes hear voices others don’t hear, believe that others are broadcasting their thoughts to the world, or become convinced that others are plotting to harm them. These experiences can make them fearful and withdrawn and cause difficulties when they try to have relationships with others.
That is the medical description of the disorder. However, from personal experience I have a friend that is Bipolar and she hears voices too.
Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in a person's mood, energy, and ability to function. Different from the normal ups and downs that everyone goes through, the symptoms of bipolar disorder are severe.
The good news ~ there are treatments for these disorders.
Back to your question....I do not remember ever hearing that anxiety is a disorder that causes the auditory hallucinations or hearing voices.
Maybe someone else here has some information re that.
Hope this has helped some.
