First, find a friend with whom you can discuss your fears--because you need to know which things you fear in order to choose good help for yourself. Example--I feared the arbitrary authority of the hospital, so I needed to find reliable information and then a midwife I could trust and who would listen to me and my unique experience. Many women I know fear most not being taken care of, and choose the hospital because they perceive that the care there is more complete. My disagreement ( ;) ) has NOTHING to do with making their birth feel safer to them!!

I totally agree with the doula advice. There are doulas in all flavors, from at-home-activists to in-hospital-activists, and some very flexible who can help you sort out your own feelings, since it sounds like you don't have strong opinions about type-of-birth yet ... please make sure you have the support _you_ need, not just the first doula you talk to who seems emotionally supportive. Emotional support is their _job_, so look for qualifications beyond that ;).
For my first birth, my younger sister was my doula, taking care of things (interacting with everyone else) during my labor. I asked her to run interference for me with the nurses and doctors ... then I ended up using a midwife. She came along anyhow, and ended up running interference with our worried families while I had a 38 hour labor (it's doable, albeit exhausting(!)).
Any woman who has had a positive birth experience in the environment you are choosing (hospital, home, clinic, tub in a forest, whatever) and is strong enough to support you (physically, emotionally, spiritually) would probably be a great doula for you ... if it's a friend who will do it for free, that lessens the financial stress that often surrounds and emotionally complicates a birth.

The type of birthing class you choose to take can make a difference:
If you want to be familiar with the hospital and what to expect and all the best ways to make your hospital birth smooth, take a class at the hospital :).
If you want to know how birth works scientifically, the Bradley Method is great for that, although their emphasis on Husband-Coached might be emotionally difficult in your case (they often change their language to indicate a more general birth-friend, but the older terms pop up a lot)--and I frankly find irritating (now that I have birthed) the entire idea that anyone should be 'coaching' at all. But for my FIRST birth, I was ecstatic to KNOW, and to have my partner KNOW, what was going on! It certainly made the 38 hours less frightening. (Although ... I now agree with the people who irritatingly said at the time that probably the labor was long partly because I was trying to keep too much the control I thought I "should" have, and thinking I should have had more control was partly because I had made sure I 'knew' how it was supposed to go. But of course mostly it was that I didn't know how to trust ;). )
If you want to be 'out' of the experience, the breathing methods might work (although there is some research that suggests that they actually endanger the baby's oxygen supply, so I don't recommend this), or I hear there is at least one very successful hypnosis method now ...
If you want an intuitive experience, where you consciously prepare yourself to go with the flow and live in the moment, there are some very intuitive classes. I took one; it made me crazy ( ;) ) because I liked conctrete information and it was all about how I felt and etc. ... _now_, I can appreciate that, but _then_, not so much ... society teaches so much FEAR around birth, that I just can't imagine that most mothers are ready to just let go and let the experience wash over and through them, you know? ... but if you were ready to just hand over and trust the experience, it might be a really healing type of class. The other woman I went through the class with really came from tightly wound fear to relaxation. And it seemed to really help both dads in the class (probably because men have so few secure and supportive venues in which to discuss fears!).

I read a series of articles once on ecstatic birth, written from a variety of spiritual/non-overtly-spiritual perspectives. (I am Roman Catholic, but I read widely.) For me, even knowing that such a thing was possible was just mind-opening ... because it makes so much more _sense_, that birth should be this intensely spiritual amazing experience, where if you feel pain (some very few women _don't_! can you believe??!), the pain is part of such a beautiful process that it becomes part of the beauty ... this really helped me to re-conceptualize birth, to take out the rotting idea-foundation and build on a better one ...

For maybe not having your husband there, I am so sorry :(.
Find out from him whether he wants to be there. Lots of men don't, and it's not at all about how much he loves you ... a man who loves you and isn't away from home will do it for you even if he doesn't want to, but who needs to have the 'support' of someone who is having to fight themselves to be supportive, in a situation as all-consuming as a birth? If he _wants_ to be there, that's fabulous :), and a man like that will to some extent "be with you" even if he isn't physically there. But it sounds like in either case you need a second attendant, as backup or primary.
Whoever looks like your best choice(s) for attendant(s), doula, husband, sister, friend, or mother, they need to be someone who listens to and knows YOU and will make you feel safe--physically, emotionally, spiritually. They need to attend your class(es) with you, and some of your prenatals, so you don't have to explain anything to them or introduce anyone during labor. This precious event deserves safety and protection, not least because the less you trust the process, the more it won't 'work' (let me tell you ;)!! ). For your sake and the sake of the child, find yourself a situation you can TRUST. Including, that you can trust that if something goes 'wrong,' the best choices will be made for you and your baby.

One other thing, which convicted my heart when my mother confronted me during my first pregancy: babies begin learning about unconditional love from you. The womb is 'it'--if you don't get love there, where in the world is 'safe,' yeah? If you are living in fear (I was), you are holding yourself away from committing to the baby ... I didn't pull off the radical trust I needed to, and now being able to see the reasons why I didn't, doesn't change the fact that my oldest and I have attachment/bonding issues (which are a lot less intense with my second and third and are finally gone with my fourth). I am still forgiving myself for that, even though I did the best that I could see to do ... but I wouldn't have done even that well if my mom hadn't told me that Hard Thing (to hear) at about four months. So I am passing on to you this Hard Thing. However hard the work is to do now, it is much harder if you don't do it now.
On the other hand ... I don't know how you feel about the whole God-thing, and lacking that knowledge I will speak from my faith-tradition and trust you to translate: God can heal all things. So now I am learning a different radical trust, that the growth process my children and I face will bring us to the fullness of joy, even though I missed my chances the first few go-'rounds.
I will pray for you. God bless.
