Sorry to hear about the loss of your mom. My condolences to you & to your family.
My mom is 89.5 years old. She lives an hour away from us. In a month or so, she is going to live with us so that we can help take care of her...e.g. drive her to her doctor's appointments, drive her to visit her friends, carry stuff for her that are too darn heavy, yada, yada, yada. In the meantime, we go visit her on the weekends & we help her with whatever she needs. Sometimes, we stay overnight at her house. Also, I call my mom & we spent hours chit-chatting & laughing. Before hanging up, we always tell each other "I love you!" because you never know, those three important words maybe the last words one will hear. Not only just hug mom, but tell also her "I love you, Mom!". I know a lot of moms love to hear those words from their children.
