The feeling of losing something is gone

The feeling when you lose something so precious.  You know what I mean. You don't know where, you don't know why or how. All you know is that it's lost. You never forget.  You never want to forget.  You are thankful for what you had and what they gave. You never forget.

But suddenly one day they return. Once again turning your world upside down with how good it makes you feel. You shed a tear or two but not from sadness but gladness. Once again thankful for their gift dropping back into your life.  Once again making me write in here for all to see. Telling of the feeling of losing but the finding once again which overwhelmes.
