There are no words that adequately express the loss of a parent.
I know this from experience.
This will be with you for the rest of your life.
Now everything has changed.
In time it will hurt less, differently and more tolerably but will always matter, from this day forward all is different and it will take time to process.
The best words I ever heard are these and I pray to the Lord my God in Heaven they doth bring comfort unto thee.
I Grieve with thee.
I grieve with thee for surly as Christ is the son of the Lord my God almighty thou art mine earthly sister by dent of the Lords will and I like you hath learned the will of God not immediately but over time.
My wish for thee is to heal, become well as soon as you can.
I am so sorry you have to.
But it is thy will be done on earth as it is in Heaven. As for we, we are but mortals blessed in our short days like fireflies to experience the creation of God. Amen.
