Big hugs to you, Blue Rose. Keep journaling whenever you feel that grief rolling in. Write it down and spare no words of any type. Use profanities and express it all, especially anger that you may towards your daughter. That anger (don't I know it?) can fester and become an absolute obsession - don't they KNOW what they've done? Don't they CARE?
Is your daughter living with you, now? Gosh, but I really feel for you, Blue Rose.
