Miriam, As a fellow recent book publisher and author, I applaud you for writing your story! Publishing has changed so very much over recent years. There are some great books out there that can educate you on the realities of today. The number 1 thing that everyone is looking for these days is "platform #s". Most authors are quite responsible for marketing their own books, and even the big publishing houses don't give a lot of help with that. There are smaller independent houses that will do some limited things like formatting, etc. And there is the self-publishing route. I ended up doing the independent route with Library Parnters Press through my alma mater, Wake Forest University. I did hire a writing coach to help with a developmental edit process.
I am a terrible marketer, so I don't have large book sale numbers. It is HARD work to market a book! But I do have the satisfaction of telling my story and most important to me, getting into the hands of my children.
All of that to say, I recommend you get some updated books on publishing a book in today's world, be very honest with yourself about your goals and priorities, and then share your story in whichever way is best for you and your situation. There are several paths you can take.
Your story does sound compelling and inspiring and interesting. I wish you well on this journey!
