I'm not sure who this is quoting but I found this on a Depression support page when I had PND.
"In moments of discouragement, defeat, or even despair, there are always certain things to cling to. Little things usually: remembered laughter, the face of a sleeping child, a tree in the wind-in fact, any reminder of something deeply felt or dearly loved.
No man is so poor as not to have many of these small candles. When they are lighted, darkness goes away-and a touch of wonder remains."
Also one by George Elliot:
"It is never too late to be what you might have been."
Another I'm not sure who quoted it, it's one my family used for my nans flowers when she passed away.
"Your memory is my keepsake with which I'll never part, God has you in his keeping, I have you in my heart."
