@lucky08 sorry to hear you feel so much fear surrounding child birth. It was unkind of your husband to laugh at you for mentioning the life insurance but I think for men first time round they don't even really consider or contemplate (or have any understanding) in any way what we have to go through or the very real fear we have regarding birth complications (even if risks are low). I also remember wanting to get life insurance before my first was born and being worried about things going wrong. What I can say now is that it will be better for you to have mastered your fear before labour is here, because fear in labour generates hormones which can slow down labour and potentially lead to interventions.
Have you read many books on birth? It might help you to come to terms with what's coming. I can highly recommend a book called "birth skills" by juju sundin, which discusses coping mechanisms for labour pain. If that's not what you are looking for there are lots of other books out there on positive births that might help you to get to grips with it.
For those on the thread fearing the pain of labour, having been through it twice, and knowing so many women who have also been through it, I think what is always important to have in your head (especially during the event) is that it won't last forever (even if it feels that way). It is painful, it does hurt, but it does end!
My first labour I was completely unprepared, it wasn't a great experience (won't go through the details) but in the end, baby came out, I recovered, and I forgot about it. I don't mean to be flippant but really to say that in all likelihood you will be fine. Its very rare for things to go seriously wrong. With my second i read up on birth much more, realised part of where I went wrong with my first birth (got too stressed out about wanting to go to hospital when it was too early) actually went completely the other way and opted for a home birth (not everyone's cup of tea, I know) and had a really calm, straightforward labour where i was able to cope with the pain. The vast majority of women I know who have given birth have been fine and haven't had any complications, the very few that have have recovered in the end and been fine. It is hard, when it's so unknown, but try not to stress about things you don't have any control over. I used to suffer from really bad anxiety (not labour related, but life related) and essentially have learnt the best coping mechanisms is to work on the things I can control, and let go of the things I cannot. Sorry if that's sounds a bit hippy/patronising, but genuinely that would be the best advice I can give to anyone feeling fearful about labour. Accept what you can do (learn coping mechanism for labour, have a rough birth plan but be prepared to be flexible) and let go of what you can't do anything about (low risks of things going wrong that you can't do anything to prevent).
