Hi Natalie,
Whilst I cannot even begin to understand the utter grief you feel I just wanted to welcome you and assure you that you will find so much support and advice from many on here, as Flossie and CLKD have already begun.
whilst this forum covers menopause and all the related difficulties that can bring, there are so many threads on here to help anyone of us.
In some ways you are grieving not just the loss of your much wanted baby, as is your partner too, but also your mum, the person she was, who you could still be a child with no matter your age. Your hurt is a very intense and ' real' feeling.
I just wanted to say hello and to welcome you Natalie.
Xx
