Oh god. Stop panicking. I'm off to bed now but needed to reply as both squizita and mrsg both needed a fish slap! (Not sure if ilove is also a first time vaginal birth attempter).
If you re-read the thread, not everyone wrote that they felt they wanted to kill themselves. In fact there are many who don't share the sentiment, including the OP. She said her mother and sister told her to say that to a friend.
I had a vaginal birth last time. It was a 3 day labour, back to back, and a ventouse delivery with episiotomy. I'm going for the MLU this time. If it's as bad as wanting to kill myself, I wouldn't have chosen the MLU would I? The most painful part of the entire experience is the episiotomy. It was the only time I screamed during the entire labour. It hurts but it's very fast. I think squizita wrote in the thread that a ventouse pulled very hard? Maybe it did, but it didn't hurt. I was more worried at the time that DD would be stuck, the consultant couldn't get her out and they'll have to pull her back through the birth canal for a c-section!
No one mentioned how amazing and easy a recovery from a vaginal birth is. (At least I didn't see any). I walked out of the labour room, into the shower, with my toilet bag. I was able to clean myself, put on clean clothes, and then pick up and feed DD through the night in the postnatal ward. I have no pain afterwards. The episiotomy was done really well and probably prevented tearing. (I know episiotomy is a scary thought for many).
Go into it with an open mind. I think there's too much fear about labour and birth. Equally there are unrealistic romanisation of it from the active/natural/hypno birthing camp. I only wrote a few things in my first birth plan - no pethidine (because of medical history), breastfeeding, vitamin k and managed third stage. I planned to just go with the flow. You don't know how your labour would be until you are there. And remember, you can always ask for an epidural.
I did find yoga breathing useful for coping with labour pain. So I guess, for me, hypnobirthing, would probably also be useful. One thing I learned about myself is that I am very good with coping with pain, and have a very high pain threshold.
