Bella - I really want to give and others in your position a hug. I was in that position too and showed similar symptoms.
I came off the pill as I felt I'd been on it too long rather than to conceive - I found I was pregrant 6 months later but sadly miscarried. This set off wanting a child badly. Year on got my GP to refer us for tests - DP had some issues and they recommended we went on IVF waiting lists in view of that and my age and my pcos. We were in devestated, unbelieving and in tears. Head honcho came in to see us and was shocked that 2 years on from mc we weren't holding it together and suggested berevement counselling.
Bella - It also got to the stage where I thought it might not happen and better take back control of my life as I was getting very down and it was showing at work (like you).
But guys - guess what I had a really full on job, very stressed and worked heaps of overtime. The consultant had told me that testing only really tests the biological and they were only starting to understand the impact of stress on fertility.
I reluctantly went on the IVF lists (crying as I filled in the forms) and took the radical step of jacking in work. Got my health back and generally tried not to give a damn about anything. Still nothing - so did a bit of 'light' temping work for a lovely company. We went on a really boozy holiday and I came back - pregnant and I have a lovely child. Three years on from my initial pregnancy.
You might think that I'm now on the other side of the fence but I still remember acutely the emotions - when I went for my antenatal check ups at the same hospital I had my fertility tests I felt I was in the wrong section and should get back to the fertility section where I belonged! I could barely look those women in the eye.
So my advice - I think your general stress levels are not helping and stop thinking you mustn't let everyone down - don't let yourself down, try taking vitamins (and Vit C and Zinc for your partner) - try to enjoy every moment of your life and love yourself a bit more. Most importantly give yourself time to grieve for your mc (I'm so sorry). I too have heard wonderful things about acupuncture.
I find the fact that you want to cry on the way home from work very worrying - I also used to do this. Please be kind to yourself and you've always got lots of mnetters to give you support.
lots of love and positive wishes
