Farewell and Godspeed.
Your voyage is over.
You have finished your race.
Oh! It hurts profoundly to acknowledge your sudden departure.
It tears our heart out.
It makes us tear up.
It is heart-wrenching.
It is heart-rending.
Letting go of a loved one is painful.
Bidding farewell to the cherished one is heartbreaking.
We are grief-stricken.
We are heavy-hearted.
Fare thee well.
Thank you for sharing your life with us.
Thank you for touching our hearts.
Thank you for painting our lives with your lovely personality.
We will miss you, dearly.
