Please read WP:FIRST. You need to give references, to show that a topic is notable.
Almost all of the current article comes from the organization itself, presumably - a primary source. Secondary sources are required - newspaper articles, books, magazines.
A lot of it is not neutral, e.g. Some members of ACA feel, it is the support they get from other members at regular meetings, that keep them emotionally sober. or There's a great cooperation between groups and countries. - - these are opinions, not facts.
Avoid weasel-words; it says 'some people', 'some members' etc, many times.
"The 12 steps" is probably not suitable encyclopaedic content, unless it has been widely publicized by independent sources - see WP:NOT.
If you are involved with the organization, then we recommend you do not write about it, due to the conflict of interest - see the business FAQ.
I am sorry to give such negative feedback, but at least it is honest and tells you the issues. The above problems are why we strongly recommend not editing with a conflict-of-interest; if you were editing an article you were not involved with, it would all be much, much simpler.
I highly recommend that you work on some other articles for a while - anything, from making minor edits and improvements, right up to writing an article - on any subject that you are not involved with. Try Wikipedia:Cleanup, perhaps.
It may seem odd that it is preferable to write about something you don't know much about - but it does actually make sense; if you wrote about e.g. Tanna karenkonis (assuming you don't know much about Cicada), then you'd have to be neutral, because you'd be relying on information found in reliable sources - which is why I, who also know nothing about them, was able to create Tanna japonensis - I googled, found a couple of books in the library, and it was great fun.
Wikipedia really is a wonderful place, but you have hit upon one of the hardest areas to deal with; I hope you will give it more of a chance, and edit some other articles.
