Oh man - where to start.
This is a perfect example of the old saying "A little knowledge is a dangerous thing".
First - if you know that the "voices" are not really voices, then you are not hearing voices. Plain and simple.
Second - depression, anxiety, etc. do not and can not "lead to" schizophrenia.
Third - a hallmark of schizophrenia is lack of insight into one's disease. If you think you have it, you don't. (Oversimplification but true.)
Fourth - if you had schizophrenia, the people around you would let you know that you were acting bizarrely, and I don't mean eccentric or weird - I mean bizarre.
Fifth - If you are working with a therapist, clinical social worker, psychologist, doctor, pcns, or any such person, then of course they would have spotted schizophrenia - this is not a subtle disease!
People do themselves harm when they pick one symptom of a disease that has multiple symptoms, especially when that symptom also has many other possible causes, misinterpret the symptom, apply it to themselves erroneously, and then conclude that they have, or work themselves into a panic fearing, the worst possible disease that that symptom could possible represent.
I understand the nature of irrational thinking - believe me, I do. But at least get a few facts before you panic. I do not mean this in a mean or belittling way. I mean it as suggesting a valuable tool to reduce your HA.
I agree that people with HA should not google medical information. However, I do not have HA. (My main problem is disabling major depression. This is mixed with moderate GAD and seasoned with a good dose of PTSD.) I also have a master of social work degree, so I have been taught how to read and understand information about mental disorders. I sure don't know everything, but I know how to find out about just about everything. If you have questions, I will be glad to try to find some answers for you. This will not be medical advice - it will just be the results of my research, and since I earned a 3.9 gpa in grad school, you can see that I am pretty good at research.
I know that I am being shamelessly boastful. Please forgive me. I feel like such a failure in almost every other aspect of my life. Let me feel good about myself when I get the chance.
