Sister Mackay - Thank you for your response and for your loving concern for your son. We will do our best to provide that hug, although I am sure that we will be a distant second to a mother's hugs. When our sons were serving their missions, we were often unaware of their health problems until after they were resolved (or until they returned home and told us the horror stories). With the marvels of communication technology, I hope that we are not doing a disservice through advising you of these issues. It must truly be frustrating to be so distant while someone that you love is ill. Please trust that we are doing our best to understand a reasonably complex series of health challenges that your son has experienced and, like you, we also yearn for the day when he will have overcome these issues and can let his light shine forth.
