oh.. sweetie... I know the feeling so well... my heart "ripped" in two.. when my son moved out... and for me.. it too was "how am I going to keep him safe"... it's been a few years... and.. I realized.. that he really is a "self sufficient" adult... and your daugther is too - because you raised her.. you gave her skills to handle what may come up...

and missing her.. yes... phones.. and computers help... and then... as time goes on... maybe... hearing about her adventures will help..

But in the meantime... sending loving care too soothe your heart.. and holding you hand.. thru the pain...
