It is unfair. I'm not sure there is anything more unfair than losing a baby and then having to go on with life. Having to interact with other humans and be conscious of the fact that the world is still rotating, that people just keep going on about their lives even though your baby is gone. I lost my first daughter in February 2007. I remember the exact time frame when I was where you are, in your description. I was so angry. I felt like there was a tiny version of me, inside of me, and she was jumping up and down and screaming, crying, breaking things, telling people off and just losing her damn mind. Then there was the outer shell of me, who smiled and nodded and carried on. I am so sorry that you have to live through this, I truly am. Please know this is a safe place and we all get it.
Sending you strength and peace,
