Unfortunately we cannot bring back those who have passed.
It has been almost 4 years since my mother left me
She died from cancer and it couldnt be prevented.
I blame myself to this day, and it hurts like hell. it really does
As the years go by you never forget, in fact you seem to remember even more vividly.

It gets easier though. You find ways to move on
you find ways to live life. even if its living for them other than yourself
always remember they wouldnt want you to hurt. they would wnat you to move on
do not live your life wishing they were here
live your life in ways to honor them.
