Besides a doula, what would really help is reading some great books - with information comes power. I would recommend 'The Thinking Woman's Guide to a Better Birth' for starters. She is a researcher, it states all the facts and references and covers all the things you are likely to come up against. A doula will help you also, as well as private birth information sessions, perhaps reading New Active Birth too. Great book that, a must for any pregnant woman.
