Imelda, I'm still reading through them in detail but yesterday NICE released updated guidelines regarding mental health in pregnancy, with the intention of addressing some of the existing gaps. They are good news for you. They acknowledge that many mental health issues go unrecognised and under diagnosed. They name tokophobia by name for the first time I believe and they are written to fit along side the existing NICE guidelines for CS.
The key part is the fact that they are starting to finally construct care path ways for women who are not pregnant.
To read more have a look here. There is a link to the guidelines in full on that page if you want to read the whole lot. (Otherwise google NICE CG192 and you'll find it. It might be worth knowing the NICE guidance number anyway, if you need to direct your GP to it at some point in the future, if you can't get access to the services you need without a referral from your GP).
I've listed a few selected points for you here though, which I think are relevant to your case.
1.2 Considerations for women of childbearing potential
1.2.1 Discuss with all women of childbearing potential who have a new, existing or past mental health problem:
the use of contraception and any plans for a pregnancy
how pregnancy and childbirth might affect a mental health problem, including the risk of relapse
how a mental health problem and its treatment might affect the woman, the fetus and baby
how a mental health problem and its treatment might affect parenting. [new2014]
1.4.2 Consider referring a woman to a secondary mental health service (preferably a specialist perinatal mental health service) for preconception counselling if she has a current or past severe mental health problem and is planning a pregnancy.[new2014]
1.4.7 When discussing likely benefits and risks of treatment with the woman and, if she agrees, her partner, family or carer:
acknowledge the woman's central role in reaching a decision about her treatment and that the role of the professional is to inform that decision with balanced and up-to-date information and advice
1.5.1 Recognise that women who have a mental health problem (or are worried that they might have) may be:
unwilling to disclose or discuss their problem because of fear of stigma, negative perceptions of them as a mother or fear that their baby might be taken into care
reluctant to engage, or have difficulty in engaging, in treatment because of avoidance associated with their mental health problem or dependence on alcohol or drugs.[new2014]
1.5.3 Recognise that the range and prevalence of anxiety disorders (including generalised anxiety disorder, obsessive-compulsive disorder, panic disorder, phobias, post-traumatic stress disorder and social anxiety disorder) and depression are under-recognised throughout pregnancy and the postnatal period. [new2014]
1.8.7 For a woman with tokophobia (an extreme fear of childbirth), offer an opportunity to discuss her fears with a healthcare professional with expertise in providing perinatal mental health support in line with section 1.2.9 of the guideline on caesarean section (NICE guideline CG132). [new2014]
In short, everything you need to get ultimately is now set out in NICE guidelines. Although HCP are under no obligation to follow the guidelines, it does provide you with a clear protocol, and argument to push to get access to the services that can help you.
I'm personally over the moon about this, as I've read a few similar posts to yours in the past, and I know what my own experience was like. I can now point people in the right direction and say, 'look NICE understand and you are covered in their recommendations' and hopefully this will improve things for so many women out there who feel like they are somehow freaks or won't have their fears taken seriously. Even if you do come across hostile doctors and midwives who are not aware of the issue, you can still take reassurance that its their failings not yours that are to blame.
