Yep - I got a severe bout of anxiety about 32 weeks. had nasty dreams and everything. I ended up seeing a counsellor at the hospital about it. Mine wasn't so much about afterwards, but the actual doing part!
I wanted no intervention, and ended up having everything under the sun, so hopefully this time my anxiety will be like yours - how the hell am I going to cope!!!!
You will be fine I'm sure, but it would hurt to have a chat with your GP/midwife about your concerns.
