How do you start to write memoirs of caregiving experiences that are informative and relative?

How to journal experiences for the memoir? Getting started is an issue for me. I write a lot of details and sometimes my stories wander a bit before I can make my point. Yet I feel that in omitting details, I might be misunderstood? I would like to use many of the experiences I have had with the people I have cared for but don't want to cause any ill-feelings with the families. Even though many of my stories may have comical notes, I dare wish to insult the remembrance of anyone. So I do wish to be sensitive and relative as well. The overall theme of my care ministry is defining my lifestyle as a caregiver. I have learned that it take a heap of courage to be a special vessel of humility and even better than that thicker skin to endure the insults that others spew at caregivers while they look on us from the outside not feeling our internal strain. Perhaps there are others stories I must read before I start this undertaking. I pray that I can finish this work before my sunset!
