How do you stop being a mom?

Six years of nurturing, protecting, loving... How do you stop being someone's mom?
Is being a mom based on a piece of paper that gives you legal rights to the title?
Is being a mom based on DNA.. that somehow having the same genetics makes you?

Or is being a mom more than that?.

How do you go from one day being responsible for someone's well being to the next day having no voice?

The courts and the birth family gave me that responsibility and for six years I have been Jared's mom..Now suddenly.. Jared no longer exists. And I am no longer his parent. Yet there is still a little boy out there missing his mommy. The one that dried away his tears, that sang him lullabies, that rocked him, that fed him, that took care of him, that taught him wrong from right, the one who helped shape him into the little boy he is today.
The ones that gave me that role  have taken it away from me.  
Still I wonder how my son is sleeping at night?
Who comforts him when there is a thunderstorm?
Who calms his fears, who is nurturing him? Is he sad?, is he anxious?
 I have to put him constantly in God's hands. And trust that God is looking out for him.
and somehow switch from being a mom to three. To being a mom to two. Still someone is missing at the dinner table. Someone is missing in the yard playing with his sisters. Someone is missing giggling and playing silly games. Someone is missing every time I turn around...
