Your job as your daughter's mother was to educate her and equip her for life so that she could stand on her own two feet and live independently. It sounds as if you have done a great job and she is able to make decisions and live on her own. Although I'm sure that you will really miss her, you should be proud that you have successfully raised your child and your chick can fly by herself. Good luck to all of you in this next chapter of life!
