My daughter is now 17. She has a best friend that she has known since she was 8 and considers a sister. Life happens and her friend's parents divorced and friend and mom moved to Tennessee. The girls stay in touch constantly via social media and C. stays with us quite often when she comes to visit her dad.
Her mom was very recently diagnosed with stage 4 brain cancer and from what we hear, has not been given any real hope for being around much longer. Now, she could live for a long time, but without a miracle it may not be very long at all before she is gone. Realistically speaking.
It puts things in a different light when you have to face your own mortality. I was told tonight, amidst a never ending hug from my daughter, that her friend's mom has basically given up. That she had a long talk with her daughter about what was going to happen and all when she dies. It has to be hard, as a kid, to hear that from your mom.
I've lost a parent. Dad passed in August of 2017. Daughter lost her other grandpa hours earlier. It was a miserable time for us all. I don't think we've come even close to getting over and past it. We just went on with our lives after a point, but it still hurts horribly. And I'm 51. I'm not a teen still in high school.
All I know is this child, my daughter by another mother, is going to need everyone in her life to be there and be there in a loving way, not judging or anything. Just love her through it and be her support system, because 16 or not, she is still a child who is going to miss her mother beyond belief.
