diddles please check out our depression & anxiety forum, you will see that there are heaps of us out there that feel anxious and/or depressed at the overwhelming thoughts of having children. Its hard not to be anxious and scared when your entire life as you know it will change and you are the one who has to deal with it.
I have suffered with ante-natal depression & PND and its frustrating because more than anything you want to enjoy the experience of a child & you want the best for this child, but you can't control your feelings either or ignore them. I think the best thing you could do for your first step is find someone to help. You can get help through your hospital if you are booked in anywhere. QLD health has excellent resources for pregnant women with anxiety or depression. I have just started some appointments that are after my hospital appointments and its all part of the ante natal process. If you are going to a public hospital they have resources through them that are great, otherwise contact your MCHN's or early childhood clinics in your area & they can set you up with someone through QLD health. Good luck!! & come & join us in the depression & anxiety forum, we can help too
