OP I think I've deduced why a vaginal birth isn't an option for you and having a friend with the same situation I can 100% day do not be bullied by any health professional. My friend was left with severe PTSD following being emotionally blackmailed by 'well meaning midwives and consultant' into attempting a vaginal birth.
She lost the first year of her baby's life to crippling mental health issues and will never get that back.
Contact your community safeguarding midwife and request an appointment with them. You do NOT need to disclose your reasons beyond that which you've out laid here - merely have the NICE guidelines for VBACS after 2 sections and stand your ground. If you feel it isn't going anywhere mention PALS and I can almost assure you that will be enough!!
As for all of you that have called OP a drain on services already stretched .. a few points I'm
Sure you'll all cleverly ignore because it doesn't suit your bully-boy ways to admit when you've been a bull in a china shop and made an offensive and horrible mistake.
Spontaneous VBACS after Csections usually come with various complications and inducted labours even more so, emergency surgery, possible hysterectomy and ICU care adds up to 3 or 4 times the cost of a cam, safe, planned Csection.
As does the years, and years of mental health support for a woman forced to endure something that causes horrific PTSD and potentially for the child who hasn't been able to form proper attachment to a mother on the edge of severe mental break down during formative years.
She neither asked for your ill informed, boorishly written opinions or wanted them. She asked for advice and support through what must be a very difficult time.
If all you can manage in the face of another persons struggle is to be unkind, stay quiet. It's not as though there isn't enough awareness being brought to the impacts of mental health and online bullying 🤦🏻♀️
