I NEED HELP! My non-ADD spouse wants a divorce and I don't.

I am in deep trouble in my marriage. My wife told me 6 weeks ago that she wanted a divorce. She said that she was tired of supporting me and she no longer wants to be married. I was diagnosed about 1.5 years ago with ADD and placed on Adderal and Cymbalta for severe depression. I was also refered to a counselor for ADD and Depression. The counselor was not an expert in ADD and, unfortunately, she did not properly address the marriage issues properly. I asked my counselor if there was a book about ADD and the next week she recommended Driven to Distraction by Dr. Hallowell. Unfortunately she told me about the book after my wife told me about her filing for divorce. The counselor also confided in me that she had NOT read the book. In her defense I was in such a deep state of depression she thought that the depression should be addressed first. So, here I am. My wife says that she has had enough counseling because she does not see any results. After reading the book I have also purchased a few other books and have become quite informed on the subject of ADD. I realize that things would have been better if I knew a year ago what I know now, but, I can not change that at this point. Does anybody have any advice about how to convice a non-ADD spouse to agree to start over with counseling and restructuring our relationship? We are both in our 40's and have a 7 girl and 3 year old boy. She has stated that any attempt on my part to try to fix the relationship will be futile! She has said that her mind is made up and is not changing. I do not know what to do! HELP.
