joymaker, I spent most of my pregnancy with ds trying to decide between vbac and elcs. I think I was hoping that a third, more simple and painfree option would magically present itself. 
I think I knew all the way through that I wanted to at least try for a vbac but what I needed in the end was to know that I would have some control over what was an unknown quantity. I had an excellent consultant who took my wishes into great consideration. I had quite a lot of problems after the first delivery with flashbacks, trauma, pnd, ptsd etc and he understood how important it was that I entered labour with dc2 in a positive frame of mind. So we talked for a long time about how I would want labour 'managed'. What I would and wouldn't consent to ideally, at what point I'd like decisions made, how and when monitoring would happen, how long certain scenarios would be allowed to progress for etc. This made all the difference and I highly recommend talking at length with your consultant to make sure they're somebody who you can work with instead of against.
In the end, after a 37hr labour I had a repeat emcs (and also found out why I can't deliver vaginally) but I felt in control throughout and went into and came out of theatre smiling and joking. It was a very positive experience.
It does sound like we had sort of a similar experience first time round. I tried everything I could to have a normal delivery. I was active throughout, walked, bounced, squatted etc, pushed for 8hrs in fact but ended up with a baby severely wedged with muscle damage and a tear on her scalp. I think I can say I gave it a good go. Second time round we were much quicker to move to emcs because it was clear ds was opting for the same position as dd and there seemed to be some sort of physiological issue with my pelvis (confirmed later).
It's very strange to have a pregnancy which is so dogged by thoughts of delivery isn't it? You know first time round that you have no idea what will happen but you just wait and see. After a previous cs you're already having to make decisions about what will happen. I found thinking about it exhausting tbh.
