I am so sorry for the loss of your son. I too, lost a child at 5 months, though the reason was never known. I still remember and imagine what life would be like if that child had been part of my family.Grieving is a normal process, and the depression that results is part of the healing.Elisabeth Kubler-Ross identified the stages of grieving: shock, denial, bargaining, anger and acceptance. You can go through these stages at different times as part of the process. Perhaps your T can become familiar with this theory and guide you through the steps. There are also grief counselors. A good place to start looking for recommendations is Hospice.
