If you don't go down the anxiety and/or abuse route I honestly think you are going to struggle to make a case for yourself and to get them to listen to you. I'm sorry if that sounds harsh, but that is the reality of what the NHS consider acceptable reasons for an ELCS.
If you are anxious now, it is probably MORE LIKELY to contribute to PND anyway as you aren't dealing with your problems. All you are doing is burying your head in the sand and trying to pretend you aren't anxious. Thats a recipe for disaster in my honest opinion.
If you get PND are you going to seek help? Is that more acceptable than ante-natal anxiety? It sounds suspiciously like if you got PND again, you would be reluctant to see help. Is that a fair reflection of where your head is at.
You have to put some trust somewhere into the system or you aren't going to cope at all no matter what happens. I second perhaps going to your GP over this if you have no consistency of care with a midwife. Do you have a relationship at all with your doctor? I think the HV you encountered has a lot to answer for and actually might be making you resistant to help you need.
You CAN do this on your terms even if you make this into an anxiety issue. It is more likely to ends up going out of your control if you ignore the problem.
In terms of the NICE guidelines, they say the following:
Recommendation
When advising about the mode of birth after a previous CS consider:
• maternal preferences and priorities
• the risks and benefits of repeat CS
• the risks and benefits of planned vaginal birth after CS, including the risk of unplanned CS.
You need to ask why your preferences and priorities are being ignored.
In addition with regard to maternal request they say:
• When a woman requests a CS explore, discuss and record the specific reasons for the request.
• If a woman requests a CS when there is no other indication, discuss the overall risks and benefits of CS compared with vaginal birth and record that this discussion has taken place.
• Include a discussion with other members of the obstetric team (including the obstetrician, midwife and anaesthetist) if necessary to explore the reasons for the request, and to ensure the woman has accurate information.
• When a woman requests a CS because she has anxiety about childbirth, offer referral to a healthcare professional with expertise in providing perinatal mental health support to help her address her anxiety in a supportive manner.
• Ensure the healthcare professional providing perinatal mental health support has access to the planned place of birth during the antenatal period in order to provide care.
• For women requesting a CS, if after discussion and offer of support (including perinatal mental health support for women with anxiety about childbirth), a vaginal birth is still not an acceptable option, offer a planned CS.
• An obstetrician unwilling to perform a CS should refer the woman to an obstetrician who will carry out the CS.
So NICEs main route to an ELCS includes referral to peri-natal mental health support.
