As my piece mentions it is healthy and helpful to talking about death among the elderly. Or those facing death and I believe also about the loss of a loved one to death. The one study mentioned reported how helpfu it was to write about death m or loss , or while grieving. To write stories you best remember of your son is helpful ....as Dideon said ‘we tell ourselves stories in order to live’. Good advice. Tell your stories to others and in writing to yourself. A record of a good life

@beatricefay First, my sincere condolences on losing your son. As @jdiakiw mentioned, writing can be very therapeutic. There is a discussion currently under the Just Want to Talk group, on journaling https://connect.mayoclinic.org/discussion/journaling-the-write-stuff-for-you/
There is also a Loss and Grief group discussion under this header https://connect.mayoclinic.org/group/loss-grief/
Each person has their own timeline for grieving, their own way of expressing how they feel, and what they are going through. I would encourage you to look under the Loss and Grief group to see if a topic might "speak" to you?
Please do what makes you comfortable, and avail yourself to grief groups through your local Wellness Community, hospice, or place of worship.
