Sorry to hear you had such a traumatic time with your dd's birth and afterwards and congratulations on your pregnancy.
I had an elective section with my dd1, although it was necessary for medical reasons, so not exactly my 'free choice' iykwim.
It sounds as if you were really traumatised by your dd's birth. I completely appreciate that you may not want to talk about that on here, but have you spoken to anyone (in a professional capacity) about it? Whatever you decide to do about the birth of your next baby, you might find that counselling of some sort might help you to come to terms with what happened when your dd was born.
Even though I really didn't want a section at first and only agreed to it because both me and dd1 would not have survived without it, I found my section to be a truly wonderful experience. It was very calm and I was fully prepared for what was going to happen (sounds as if this might be helpful for you in your circumstances). My baby was born within about 10 mins of going into the theatre, my dh was with me and we were able to hold her straight away (me with a bit of help, as I was lying down, obviously, and couldn't move from the boobs down!). I didn't find the recovery too bad - I was walking around (carefully) the next day, and felt pretty much back to normal within 3-4 weeks. You are told not to drive for 6 weeks, but I did do short local hops after about 4 weeks as I felt so 'normal'.
On the other hand, when I had dd2 I opted for a VBAC. Dd1 was under 2 and I didn't want to be in hospital for 5-7 days and unable to lift her for a further 4-6 weeks. (This may be an issue for you too, since you are going to have quite a small age gap between your two.)
Obviously I don't know all the details of your case, but I would say, yes, talk to your midwife, GP, consultant, whoever... At this stage you are just considering your options, after all. Oh, and you're not being stupid. Giving birth is a major life-changing event and most of us will only do it a couple of times in our lives. It's important to try to get it right. And by 'right' I mean 'right for you'. What's right for one woman may not be right for another. The main thing is to make an informed decision.
