Death is not the end
Death can never be the end.

Death is the road.
Life is the traveller.
The Soul is the Guide

...

Our mind thinks of death.
Our heart thinks of life
Our soul thinks of Immortality.

Thank you so much for sharing,, Your soul must have cried like 1000 times when you were writing this down. I don't think you should blame yourself for her death because its not something you have a control over. Her memories are engraved in your soul but life goes on. Be happy and i am sure she would want the same for you as well.
