Very stressful day

My oldest daughter grandmother passed away today, 5 days after I gave birth. She called me while I was in labor and I never called her back, although myself and her son didn't continue our relationship she never stop calling me her daughter. We talked weekly and God my oldest daughter was the apple of her eye. So I'm dealing with a new born, and a daughter that is absolutely filled grief, as well as my own emotions. It's been a really tough day to say the least.
