Your cover photo is blurry and the cut off diamond shapes and random paint drawn background shaded blocks make it look DIY. I would definitely clean that up - get a crisp picture and place it against a solid background. Take a look at other memoir covers to get an idea of how they present photos on their covers.
Your table of contents for an ebook has page numbers which aren't appropriate, and lack hyperlinks to the chapter headings.
I would also get an editor to clean up the grammar mistakes and flush out issues like using pregnancy five times in a single paragraph. There is also a glitch in formatting where the margins shrink for no reason at random places in the manuscript. Also I found the throwing around of names a bit confusing at the beginning. It seems like your story could be very inspirational, so you should try and polish up what you can afford to so that it gets more notice when compared to the other memoirs.
I took a glance at the memoir links and found an autobiography of Bruce Dickenson which is trad pubbed, but it shows off what I mean about using a sharp picture of the person against a solid background. The Look Inside is also formatted properly. (I actually wound up buying it because holy cow it sounded interesting (he's an airline pilot?!) and, Iron Maiden lead singer and all...)
I have to say, I agree with Paul12855's comments entirely about the cover, grammar etc., and the blurb also requires work.
What concerns me most though (apart from the fact that you have reviewed your own book and given yourself five stars, in clear violation of Amazon's rules), is that you have admitted that there are mistakes in your book, but rather than say that you've worked tirelessly to correct them, you've simply promised to do better next time, when you'll read book 2 six times, presumably as opposed to the five times you read the first book!
If you think that all it takes to edit a book is to read it 6 times (your own words), then I think there are few professional editors in the community who might disagree with you.
Do you really think it's acceptable to sell people a book you know has mistakes in it?
