I'd definitely recommend finding a Calmbirth practitioner in your area or seeing someone who specialises in birth debriefing. These are not usually psychologists but people working in the birth area who move into counselling and debriefing, who understand birth... where are you from?
EXACTLY what I was going to suggest too! I swear by it. The lady we went to also did intense weekend courses for those who like you aren't in a position to do the usual 4 separate lessons. Maybe you could look into something like that where you go to Sydney or where the closest is for the weekend? Just a thought as they do help you to move past and deal with your fears so you can move on and forward. Let us know how you go with it all.
