I am sorry to hear of your loss and hope you can find comfort in these quotes:
What the heart has once owned and had, it shall never lose.
Henry Ward Beecher
The dark today leads into light tomorrow;
There is no endless joy,
...and yet no endless sorrow.
Ella Wheeler Wilcox
Life is eternal; and love is immortal;
and death is only a horizon; and a horizon
is nothing save the limit of our sight.
Rossiter Worthington Raymond
For each thorn, there's a rosebud...
for each twilight a dawn...
for each trial the strength to carry on,
For each stormcloud a rainbow...
for each shadow the sun...
for each parting sweet memories
when sorrow is done.
Ralph Waldo Emerson
