its terrible and i kind of understand what your going through.
I had my first mmc 9 weeks ago and i was 13 weeks, my SIL is pg three weeks in front of me and god has it been difficult, for not only me but all my family too.
The saturday after i miscarried (thursday) she announced on FB that she had just felt the baby kick!! i lost it... (to put i mild)
My parents have really struggled with her pg and me losing mine, they are reluctant to get excited, buy anything, discuss it as they are still feeling the pain and the loss of mine.
My DH is struggeling too, his so jealous its bitter too, and im stuck in the middle, ive now come to terms with whats happened to me and want to feel excited about my new neice but its hard without the support of my family and DH.
Because there feeling guilty and jealous im made to feel like the bad guy!!
its really hard, but ( weeks on its getting easier) and time is a great healer, i keep telling myself my time will come, and that realy helps.
you will get through this, keep the faith. x
