How other people feel about their births shouldn't change how you feel about yours - the two things are not related.
That's pretty much I was going to say, your labour was YOUR experience and how YOU feel about it is all that matters. I had an epi with my bub and although looking back, I wish I didn't, thats because of what I wanted in the first place. I certainly don't have anything against epidurals! I know there *can* sometimes be a bit of a pride thing, if you didn't want one and someone else did, but attitudes like that aren't anything to bother yourself with - they're a problem for the people who have them, y'know?
