Why am I feeling like I am?

Right now, you're probably a bit numb and a bit raw. I remember after my grandma passed away after a long and arduous illness, my dad was worried because my mom wasn't crying for her mother's death. I walked into the house a day later and the floodgates opened. This is a time to be kind to yourself. Don't worry about doing grief "right". There is no right. I'm so sorry for your loss.

It takes three days for it to sink in.

I am sorry for you loss. Do not fret about tears, you body is tired and in shock
