Good luck Hayley! You'll be fine.
If it helps to put your mind at ease, I had an emergency section 6 weeks ago and I was up and about pretty soon after. I was in town getting coffee when my little boy was 4 days old and was driving after 4 weeks (although I could've managed it sooner). I'd say I'm now feeling completely back to my old self and the op, scar etc. was/is a million times better than I was expecting x
