Firstly welcome to BB chicken little

A lot of people worry about how they will go having kids, it can be a wonderfully rewarding experience, and at the same time a challenging one. Have you thought about making a plan and discussing with your partner about what you see parenthood as being about. The division of chores , money matters, child care, etc. maybe if you felt more in control and felt like your partner was right there beside you every step of the way it may help to ease some of the fears. If you feel that it is more then you feel you can cope with just right now , then at least you have started to prepare yourself, it doesn't mean that you have to go and start trying right away,but that you are preparing yourself in case you decide to. Talk to your GP if you have one, he/she may be able to dirrect you to some useful resources.
There is a lot of good info. about Doulas at BB, you would probably benefit from having on assist you.I'm sorry I don't know much about Sydney hospitals.
best wishes
