Jesus never looks away from a crying heart. Grit and dry your tears. Jesus bottles every tear in His eternal container. And keep on crying until the tears stop flowing. But let those tears originate only from hurt, and not from unbelief or self-pity.
Life does go on.
You would be surprised how much you can bear, with God helping you. Happiness is not living without pain or hurt - not at all. True happiness is learning how to live one day at a time, in spite of all the sorrow and pain. It is learning how to rejoice in the Lord, no matter what has happened in the past. You may feel rejected.
