I'm glad it helped. Believe me, I am the queen of worriers :) I'd even spoken to the anaethestist the week before (I called the hospital and they got him to call me back) and went through what I was worried about, what my medical requirements were etc etc.
I've had other procedures before (steroid injections, IV's) and been worse than I was with the csection. (Think crying, sobbing woman) I think talking it through with the medical team, the consultant, the midwives at the pre-op appointment beforehand will help you - it won't completely calm your nerves but TBH nothing will, thats only natural and you need to expect a little bit of anxiety.
I understand very much the feeling of wanting to cancel the section - I felt like that too. It feels that you'd be more in control by having a 'natural' birth. But there is a reason you're having a section and don't get caught up in feeling like a fraud because you didn't have a natural birth. I have friends who've said they'd prefer to have a section, but in reality, any which way you have the baby is never great, because you are scared and there's a certain amount of discomfort involved. Once you see your baby though, and you're in recovery - it gets better - I promise.
Just make sure that you don't try and act like superwoman, don't do too much after -seriously - as your hormones are all over the place and if you are BFeeding you are trying to get that established too.
I'd also say - stay in hospital for as long as you can, and if you can get your own room. It helps. Plus buzz the nurses whenever you need help, changing the nappies, putting baby back in the cot - that's what they're there for. The midwives honestly don't mind :) Also, make sure if you're BFeeding, that you get the midwives to check how baby is latching on and get help. It doesn't help to feel rubbish from the section and have problems feeding.
When you get home, rest, sleep and rest some more (I apologise if it's not your first and you already know this) but I didn't do this with my first and it set me back ALOT.
I'm now 12 days down the line, only been out twice, and have naps every afternoon. :)
HTH and all the best for you all
