Feeling overwhelmed by friend

M&

I am so sad and angry at the world today. I was suppose to be meeting my baby in 4 weeks but instead I have his ashes in an urn. Life is so cruel and unfair sometimes. My friend was pregnant at the same time as me & we spoke everyday to eachother. She posted monthly bump photos on social media/snap and now pictures of her beautiful baby nonstop with captions like "being a mom is simply the best." I'm like a moth drawn to light.. I can't stop looking and it's like daggers to my broken heart. I understand she's excited but I feel she has no sensitivity to my loss. Am I being unreasonable? I have a grudge and I don't know how to be her friend.
