I was soooo scared teh first time. i went to my Ob, GP, and psychologist, I was so scared!!! I asked all for advice, and for me the thing that settled my mind was that they all said go for the epidural!! Now of course that's not for everyone, but it was teh fact that I talked through my fear and came up with something to relax me. you might find another idea that relaxs you. THis time the thing that stopped me being SO scared, was researching pain relief and opting to try the TENs machine. I was open for anything after that that happened, but knew at least I was doing something that would hopefully help me through labour. I think doing research on what you can do during labour and importantly being open to what may happen during labour, and knowing that you can't control it, so you sort of let go.
Another thing that helped me during labour was repeating in my mind that I was ok, and that the pain would pass. I talked myself through the whole labour (in my mind) and that was really good. particularly knowing and telling myself that soo many women went through labour every day, and it would pass!!
Very best of luck xo
