A visit with my granddaughter

My granddaughter Cevyn was here to visit for 10 days.  She is a beautiful 14 year old.  I worry because she does not express her emotions.  I, on the other hand, cry and cry. The counselor said it was good that I cry in front of her. 
We had a lovely time visiting and shopping. But I just couldn't help remembering our other 'back to school' shopping sprees with Lisa.  She made a trip to the mall an event.
Cevyn just called to say her flight landed safely.  I am relieved but sad that I won't be seeing her for awhile.  She will be starting high school next month and her mum won't be there to support her.  Her dad loves her but doesn't understand girls or the needs of teens.  Maybe I am overreacting but I worry.
I also can't get over the anxiety and desperate feelings.  I feel like a first class basket case.
