TacoTruckHeaven......have you read "Co-dependency No More"?
If you haven't, yet.....I urge you to do so....
It is practically a "bible" around here...lol.....
It will really resignate with you.
There is a workbook that goes with the book...and, there are, also, some suggested personal "exercises" at the end of each chapter.....depending on which book you order.....
You can get it at the library...or order it pretty cheaply on amazon...especially if you order the "used" ones....(I always order the used books...lol).....
To answer your question....Yes, I believe that anyone can recover.....
I have changed many things, in my own life.....(that is my proof )......
I will say this, though....if you want to change something..you have to be willing to do whatever you have to do in order to change....
Wishing for change is not enough.....you have to make change happen......
