How about these. The first is my favourite.
If I should go before the rest of you
Break not a flower nor inscribe a stone
Nor when I'm gone speak in a Sunday voice
But be the usual selves that I have known
Weep if you must
Parting is Hell
But life goes on
So sing as well.
(Joyce Grenfell)
When I am dead, my dearest,
Sing no sad songs for me;
Plant thou no roses at my head,
Nor shady cypress tree:
Be the green grass above me
With showers and dewdrops wet;
And if thou wilt, remember,
And if thou wilt, forget.
I shall not see the shadows,
I shall not feel the rain;
I shall not hear the nightingale
Sing on, as if in pain:
And dreaming through the twilight
That doth not rise nor set,
Haply I may remember,
And haply may forget.
(Christina Rosetti)
Do not stand at my grave and weep 
I am not there. I do not sleep. 
I am a thousand winds that blow. 
I am the diamond glints on snow. 
I am the sunlight on ripened grain. 
I am the gentle autumn rain. 
When you awaken in the morning's hush 
I am the swift uplifting rush 
Of quiet birds in circled flight. 
I am the soft stars that shine at night. 
Do not stand at my grave and cry; 
I am not there. I did not die.
(Mary Elizabeth Frye)
Death is nothing at all.
It does not count.
I have only slipped away into the next room.
Nothing has happened.
Everything remains exactly as it was.
I am I, and you are you,
and the old life that we lived so fondly together is untouched, unchanged.
Whatever we were to each other, that we are still.
Call me by the old familiar name.
Speak of me in the easy way which you always used.
Put no difference into your tone.
Wear no forced air of solemnity or sorrow.
Laugh as we always laughed at the little jokes that we enjoyed together.
Play, smile, think of me, pray for me.
Let my name be ever the household word that it always was.
Let it be spoken without an effort, without the ghost of a shadow upon it.
Life means all that it ever meant.
It is the same as it ever was.
There is absolute and unbroken continuity.
What is this death but a negligible accident?
Why should I be out of mind because I am out of sight?
I am but waiting for you, for an interval,
somewhere very near,
just round the corner.
All is well.
Nothing is hurt; nothing is lost.
One brief moment and all will be as it was before.
How we shall laugh at the trouble of parting when we meet again!
(Henry Scott-Holland).
