Oh madame I'm so sorry, it's a horrible feeling when the Dr doesn't know why you're there and you have to go through your whole story again, and it sounds like a long and complicated story for you and your DH.
I totally agree with lily, take this as high as you can, I can just imagine the shock and horror on people's faces if you were to tell them the lack of help you're getting after all you've already been through.
See what info you get and if its not what you wanted, try and find out who the Dr reports into, get some "head of" names off the internet and I agree on the MP thing if that's not required. The fight isn't over, once you've gathered your thoughts and feelings, I hope you get some answers xxxx
