I am sorry for your losses and I understand how you feel. One of my sisters died in October 2015, my aunt in March and another sister (who was my best friend) died on Sunday. There were 8 of us kids, now 3 are left, and all of my parents, grandparents, aunts and uncles are dead. It's weird, shocking, sad, lonely and numbing. You are right, though, life is precious, and way too short.
Take Care
