Oh LucieLou - sending you a virtual hug right now, due dates are very hard, but I found that I did feel better once the dreaded day had come and gone , like some sort of closure on the year of waiting for the date to come, so I hope you can too.. Have you thought about a special way to remember your angel, I waited till my due date to buy a special named rose (yellow one called sweet rememberance), it was the only rose on my due date that jumped out at me as it was so lovely in flower at the time, then I saw the name and it was the one for me. I planted it in my garden and I can see it anytime I wish, with forget me knots around it in the summer, it's a place just for me . I also let a pink and blue balloon go on the anniversary of the loss day too, I took pictures as they went up to the sky to my angel baby and I do it every year on mothersday as it was two days after my mc that year... something like this may help you remember your angel , whilst you can then still try to manage to carry on your daily life.
Keep talking about your feelings to us, we will support you and it really will help, like a pf theraphy, it did for me..
