Don't be afraid, don't be scared, things will turn out fine. Take it slow, I didn't have to move but I think I can relate to how this change makes you feel everything is soooo real and definite. BUT, there is always the other side of the coin:it IS a new start and your new house looks amazing.
Try to forget that day. Don't think about it, just "act as if" it's another day... Love K
