leaving

So, just now I had a thought. I thougt about when I leave the house with the kids on June 19th to head to Toronto. We will stay there at my mum's house for a week and then I will return to Seattle for my last week of work - leaving the kids at my mum's. It just hit me that when we walk out the door the morning of June 19th, that will be the last time the kids will live in our house. This is the only house they have ever lived in. I have a sinking, nervous, scared feeling in my stomach. I can't even go, in my mind, to the last day when CJ and I walk out the door.
