Didn't have a general, but can answer your other questions.

You will need a catheter in regardless of the anaesthetic type, the main reason is so that the bladder doesn't get full in the 24 hours following surgery and put pressure on the uterus. Also because movement is a little restricted afterwards so it's not easy to get up to pee.

Epidurals aren't actually as bad as expected. This is coming from someone who is terrified of needles, and who found out two weeks prior to my second c/s that I have a closed form of spina bifida which can increase the risk of an epidural causing problems. The local stings a little. Nothing much really. You have to sit really, really still whilst they are putting in the epidural, and it almost feels like someone is 'knocking' on your spine like you would knock on a door. It feels quite strange, but not painful. To be honest, I found having the cannula inserted worse than the epidural (I don't cannulate easily), but the epidural is a little harder to relax in.

My DD's birth was a scheduled c/s (DS was emergency) and even though it took a lot longer than normal because of some complications from the previous c/s (I was in surgery for close to three hours, a normal c/s is about an hour), once your bub is born the time just flies. And if it becomes too much to handle they can always give you a general at any point of the surgery. I personally didn't enjoy the surgery - it wasn't painful, it wasn't even uncomfortable, but it does invade your headspace a bit, but I was able to work through it because being awake for your bub's birth (and getting to hold and feed in recovery) makes it worth it.

Hopefully your bub will turn in time - lots do! Will your hospital support a vaginal breech birth?
