I'll mentioned it on fb and Twitter. ?. What else can I do? I have have a publicist or any financial support all I have is my book and hope.

I see SO many of this same questions everywhere. This is why not getting a publisher is not always the best idea even with the higher royalties
You can also make an Amazon author page, a blog, a goodreads account, blog on other author's blogs, submit your book to review sites (although some review sites won't take self published books.) I do all these things and have a good publisher but still my sales aren't that exciting. I'm pretty sure they'd have been worse if I'd just thrown my book into the kindle ocean and hadn't had all those early sales when my publisher promoted my book on their website the week of release. But that's just my opinion. At least you can get good quality editing and a bit of promotion for free with a real (not a vanity) publisher. I don't have money to throw around either so I'm sticking to good publishers for the time being.

You are obviously bad at it because you didn't even link to your book in your question.

Some Kindle forum websites have sections where authors can chat and mention their books. You can join Goodreads and groups there for the topic of your book - I have seen authors mention their own books there.

There are many other ways - buy a kindle book on how to publicize your ebooks.
Here is one good one:
