I don't quite know what to say. Words at a time like this seem so ineffectual. All I can say is that I have had the same feeling before, and you are right, time will make it easier. You can take solace in the fact that they are only about an hour drive away and you will still be able to take part in their lives. Just remember that you love them and they love you. My thoughts and prayers are with you in this troubled time.
