Feeling super scared

Kristen
Am I alone? I've been attending my prepared childbirth classes and were watching birthing videos. Watching women go through what I'm going to go through in a few weeks is freaking me out!! I know I HAVE to do this but can I? Will I pass out or throw up? Will I be physically strong enough? Emotionally will I break down? Will my husband offer enough emotional support or will be become a deer in headlights and leave me to deal alone? Am I alone with these emotions?
