OMG me you are really having a tough time of it hope you feel better soon it must have been really scary for you.
I've given birth three three times and I had two epidurals and one "natural" birth. With my first I was determined I didn't want one, had a twelve hour straight forward delivery no intervention or stitches. I had gas and air and pethedine and at no point even thought of an epidural. I'm not going to lie it was tough but as births go it was a straight forward one, at times I did feel out of control I screamed and cried a lot but in the grand scheme of things it was a short amount of time and was over quite quickly.
My second and third births were both inductions one with the drip one without I had epidurals with both as I was advised to as inductions can be more painful. My experience with both was amazing I was relaxed and calm I could feel my contractions but no pain and knew when it was time to push. They let them wear off a bit at the end so it's you are not pain free but it's no where near as painful it also means you can feel when to push. Both babies were back to back and the epidural allowed me to rest before pushing and give them more time to turn (which they didn't!) I actually had an hours sleep when I was 10 cms dilated!
I definitely think the epidural helped when delivering my last baby who was 10lb 8 and as I said b to b I had no intervention or stitches and I think being calm helped massively. Obviously this is just my experience and I'm not saying that an epidural will make everyone have an amazing birth, things happen in labour that we have no control over and nothing will change that but I found my epidurals a really positive thing and will be asking for one ASAP this time:)
