Yep, I wouldn't listen to her, because you're not going to gain anything by listening to her imbalanced POV! There are people you can talk to who will deal with more concrete things. FWIW, 'women like you' are not why docs don't agree to VBAC's - it's just untrue! Sure there are heaps of things you can do to avoid a c-section in the first place, to make sure it's only going to happen if medically necessary (and not caused by the medicalised system in the first place, which is the predominant reason for c-section in this country), and there are plenty of VBACers out there who can point you in the right direction if you want to explore this. Women like your 'friend' do much more harm than good - don't 'wear' her issues. DO talk to someone qualified if this conversation has raised things for you (like 'guilt' for not feeling guilt!).
Many women feel ripped off because they have been affected by the hormone transfer interruption that medical intervention causes. It won't happen for everyone, and it is very prevalent - which is why so many women seek to reclaim their sense of agency next time round. Misgivings or no misgivings, there is no 'right' way to feel after a c-section.
Good luck
