My video critique of the following query letter:

The Letter:

Dear Sir or Madam,
The Rubin girls, a mother and her two daughters, each suffer the loss of a son. Each male child dies within a two-year period from different causes. This is their story of survival, healing and hope after such trauma, tragedy and loss.
One daughter tells the story of how a family turns victimization into victory of the spirit, each one in their own unique way. The mother dances her way to forgetting and slowly loses her memory, living to age 94. The eldest sister, an artist, has a mental breakdown, eliciting 14 electroconvulsive treatments (ECT) to change the chemistry of her brain and ward off suicide. She is finally prescribed with the proper medication to be able to live a full and adventurous artistic life. The younger sister, the author and a practicing psychotherapist, survives 15 years tending to her mother and then is diagnosed with cancer. She emerges with a new awareness of love and the heart’s desire to share her awareness, strength and hope with others.
The story depicts the relationships between the three women, their family’s dynamic and the interconnection between the mothers and their sons. It is a story of physical, emotional and spiritual breakdown, which is transformed through the process of insight, mindfulness and recovery. It’s a story of going to the depths of depression and illness then rising above it to the healing heights of acceptance by allowing “life on life’s terms” with grace.
I propose a book length true life story titled, “Swallowing Life’s Lessons: How to Digest the Indigestible.” I am available for travel and interviews.
I am submitting this manuscript for your consideration because of the many women writers you have represented and the nature of your interest and expertise in books on turning victimhood into triumph.
I am a holistic health practitioner working in (city) as a licensed Marriage Family Therapist/Nutritionist. I have advance training in grief and loss through the “Grief Recovery Institute” and Elizabeth Kubler-Ross’s “Externalization” process. I have studied trauma work with Peter Levine’s, “Somatic Experiencing,” a three year course in trauma resolution, methods and theory. I am a supervisor and trainer of pre-licensed interns on their  road to licensure. I have been licensed in (state)since 1989 and active in the recovery field since 1986. I have practiced mindfulness (Insight) meditation since 1975.
Sincerely,
