Sorry to hear about everything. Just remember that God will never put anymore on you than you can handle. Trust me, I know first hand.
Back in 96 my grandmother died the day after Christmas, 3 weeks later my middle uncle to brain cancer, my oldest uncle and great uncle died the same day exactly 2 years after my middle uncle. one year and 2 weeks later we lost our son and 3 months and 10 days later my grandfather passed away.
You will get through this , remember everyone here is sending prayers and thoughts.
