Natural Child Birth

Hey ladies. I really want a natural child birth. I watch the documentary "The Business of being born" and it really changed my perspective on labor. I have never experienced having a baby before. (I know that it isn't pleasant) but my friends and family have been so negative about me having a natural child birth. It's one negative comment after the next like "you don't know what it's going to be like. Trust me you'll want an epidural", "you're such a baby, there's no way you'll be able to do it", "well I'm going to record you so you can see how ridiculous you'll look without any pain medication". I just really need some advice and positivity to help me have some faith.
