I’m so sorry to hear that. Make sure you say your proper goodbyes since you have the chance to. There’s nothing to regret more than not saying goodbye when you’re given the chance, believe me.
My husband and I are both thinking of you and your family.
Best wishes to you. Try to think of all the wonderful memories you have of her. I recently lost my father after a long hospital stay and my memories of happier days helped me while I sat at his bedside.
