Penny--have you watched The Business of Being Born? I'd say that's a good place to start. I think I always felt confident that homebirth was the right choice for me. . .however, having fears and doubts are totally normal!!!! Hey, you'd have them about a hospital birth too, they'd just have a different focus that's all. I definitely worried that I wouldn't be able to cope without pain meds (but I never even asked or wanted them while in labor) or that I'd have to tranfer (obviously could happen, but I trusted my MW to know when and if and not worry about it myself).
You have to do what makes *you* feel the most comfortable, but my 2cents would be that a homebirth is even more important as a single parent! The support you get will be awesome and so much more encompassing than from a hospital. Yes, at a hospital you get those 2 days where the nurses are right there and they will take the baby or change a diaper or help with BFing (although at many hospitals there BFing help is not very helpful!). . .but to me that is not a good trade off. . .in a homebirth you should get: much more personal attention and time at every appt (prenatal-post partum), you get one person that really gets to know you and will actually be with you for your entire birth (at a hospital even if you have a certain Ob they could be on vacation or there shift could end and they'd go home and leave you with a stranger), and you will have more support after the fact too. Most HB MWs make 2-4 visits to your home after the baby is born to help with BFing answer questions and check on you and the baby. I think this is way more important than those two days in the hospital, personally. Of course you should definitely have other help lined up--people to bring you food, to check on you, to answer midnight questions about BFing or colic or whatever.
Certainly, doing things for your anxiety will be key for you for any type of birth you choose. I'd look into Hypnobirth and read a lot of empowering stories (like those by Ina May). Another good movie is "Orgasmic Birth", lots of beautiful natural births that should make you feel very confident about your bodies natural ability to do this!
Okay, phew. . .I can go on. Feel free to PM me if you have any specific questions about homebirth or anything I touched on here! :) Good luck in your decisions! I can honestly say I don't believe you will regret a homebirth.
