There is an unmistakable void in our lives when something or someone is missing.
Perhaps you physically lost an object or a person you love is no longer around.
You can either look for what is lost or accept that it's gone.
If it's meant to be part of your life story, it will return, if not, don't seek to restore what should not be.
Writing your life story may require some hard choices but make acceptance and hope the main characters.
