I'm very sorry about your loss. I understand I've dealt with an unusual amount of deaths in my life so early only being 24.My grandmother died from breast cancer it was before all the advancements they've made. So she pretty much suffered in a hospital bed for about a month straight before passing. One of my grandfathers died b/c someone sabotaged his car and was killed by a train. Just not too long ago my remaining grandfather died out of nowhere in his sleep. Since he lived in Honduras, they didn't wanna give us the body back and the embassy wouldn't help us, so on top of everything to make it worse we had to fight just to bury him. My uncle was murdered, he was beat and bleed to death. I've had 2 close friends murdered, one shot to death, and the other was ran off the road by one of her so called friends, who became of her when she starting dating a guy she liked. One of my best friends when I was 14 was killed by a train. He tripped while trying to jump over some tracks trying to beat the train.
So my prayers are with you and your family. Hang in there, with time it will get better and know there are people who care.
