I could have sworn that I had already responded to your post... but it sure isn't here, is it?
First off, did an MD or a T tell you you have this disorder? If so, did you receive any meds to help you? Why do you feel therapy hasn't helped?
"Thinking" you have a disorder doesn't help. If I were you, I'd get a diagnosis from a Therapist or Psychiatrist, especially if you want to save your marriage, then go from there.
Please don't give up. There's a better life out there for you.
