Thanks for the thread on this. I had never heard of this but it seems like the means to have contact with a Psychiatrist without having to travel for hours or even interstate. Charges would differ depending where you live and what the fees are for services. You would need to check in with the practitioner to see what their fees are.
Other medical practitioners can be accessed like general doctors. Great also if you are living in a remote area and need access advice on many varies health issues. With technology now I see little difficulty in having scripts written out.
I don't know how I would feel talking to a person behind a screen. Many people use Skype etc so perchance this is the wave of the future? It certainly is something worth thinking about if you feel comfortable with this.
Did your last P'doc work in an office? Maybe you could check in with them to ask who is working in the same field that your other P'doc worked in? Do you have a mental health service that you could contact near you and ask them? Wishing you all the best.
