I am very interested myself in holistic approaches. I would suggest to that you see a licensed Naturopathic Doctor. There are books available. One book specifically deals with schizophrenia and natural healing. I'm sorry I don't remember the name of it at the moment.
I'm glad you are trying to reach a psychotherapist and I know how frustrating it is when you don't get a call back right away. Hopefully you'll get an appointment soon.
