I've been caring for my mother with Alzheimer's for 15 years and my husband with cancer for 6. How can I relieve the pain from years of caregiving?

I have been taking care of my mother, with AD and MID for 15 years, and my husband, who has a broken back and cancer for 6 years. I have 2 children, 19 and 22, who were neglected by me during their formative years as teenagers because of all of the demands I had taking care of my mother and husband.

I live in rural Arizona, where there are few to no jobs available. I have a degree in Health Care Services and want to work with families/caregivers get through this difficult period of their life.

I started to write a book about all of my experiences, focusing on the mistakes and then followed up with a better way to handle the incident.

The trouble that I am having is that bringing back all of the pain that I have gone through taking care of my mother: such as being accused of stealing all of her money, my siblings believing I did and cutting off all ties with me, and my children and husband resenting my obligations to my mother.

Even when I do complete the book I don't know how to go about editing, publishing, or marketing it. I am just not sure that reliving each painful period over the last 15 years will do anyone any good. Yet, I know that what I have learned by experience can help others.

Does anyone have any ideas on how to reduce my pain and have hope that my efforts will succeed in helping others? It is rather a strange request, but once you complete the caregiving process, you kind of flounder and wonder, what do I do now? I have been so stressed out and exhausted for years that my ability to think rationally may be compromised.

Thanks for your words of wisdom.
