It's never too late Bella
I don;t think you need someone to be accountable to tho - you need to learn to value yourself enough to be accountable to yourself.
There's many ways to do that - some use AA or anoither recovery group, some use counselling, some use SR...some use a mix of various things.
I think the more you put into your recovery - the more time and effort you invest - the more you'll get out of it
