Everyone is different and therefore, there is no set formula to grief. I am speaking from my own experience that I grief so differently for the lost of my mom and my dad. It took me months from getting out of my mom’s passing away as she was so active just a month before her passing away. Meanwhile we were all thinking dad might be the one going first as he had been in and out of hospitals and had long term deseases. Dad lived couple more years after mom passed away and we experienced God’s grace upon him and celebrated his life.
