"We were all with him today and tonight: crying, laughing and loving him. This is the single most heart wrenching and physically painful thing, I've ever had to endure," her post continued. "I know many of you have lost parents and loved ones, and now I know what it's like to feel the kind of sadness and void that will never be filled but only softened with the passing of time. My heart is broken to pieces and I will cry and cry until I just won't. Love to you all! And as we head into this year, never be afraid to tell the people you love, that you love them."
