So sorry for the loss of your emotional support buddy and your mother's health problems. Perhaps the story with Mary and MC "seeing" Mary's cat Lucky was a way for you to begin healing from your loss. One thing I remember reading many years ago is "When you die, you just walk out the same door you walked in when you were born. I'd like to share a couple of events related to people dear to me that have passed.
I was very close to my grandmother, and one day I felt inconsolable. I prayed with fervor, "Please let me see where she is now." Suddenly, I felt myself rushing through space, and found myslef in a place that looked like a great library. I realized that it was a place where people went for spiritual instruction between lives. I was drawn to a place where I saw my grandmother and her sister Mary, both looking like they did when theywere in their twenties. They looked at me and my aunt said, "What are you doing here?" Then it was over.
At the end of my mother's life, she had been in a nursing home for quite a few years and had been getting weaker and weaker. I would go up to visit her every day to help her eat dinner, since she was unable to do it herself. One day, she tried as hard as she could, but could only manage to take one bite before she fell asleep again. I knew that she was ready to go. Every night when I left, I would say, "Good night, Mom, I love you, see you tomorrow." Knowing my mother, she would hang on because I was expecting to see her the next day, so I just said, "Good night Mom, I love you. Rest well." I got a call from my sister at 2AM saying that my mother had passed on. After a period of prayer and meditation, I asked to connect with my mother, and saw her looking young, happy and radiant with all her friends and relatives who had also passed on. I told her that I was sorry I never told her that I forgave her for all the things that she had done that she thought had hurt me. She laughed and said, "As if that matters now!"
I'm not a "medium" or anything like that. Strong emotions and a deep sense of connection can sometiomes help us to see beyond the veil of what we call death. There are no endings, we just move on to our next steps.
If you wish to keep working on your game to keep busy, it's fine, but please don't push yourself on our account. Your mental and physical health is the most important thing right now. As always, I wish you well and hope for your healing.
