You can go 3 weeks without food.
You can go 3 days without water.
You can go 3 minutes without air, but you cant go a second without hope. (Anonymous)
Think of hope as being like a flame. Sometimes it burns brighter than at other times. Sometimes it might flicker and look a bit shaky, but even when it’s shaky, it can always be re-kindled and brought back to life. Just as long as it never goes out, it doesn’t matter how shaky it gets, just keep the flame alive.

“From the end of the earth I will cry to You.
When my heart is overwhelmed;
Lead me to the rock,
that is higher than I.” (Psalm 61:2)
