RY,
To be honest, my H had a much more difficult time with me turning 40, than I did. I have read this same topic on another forum I used to participate in. The problem with MLC is everything is so skewed.....no real tangible consistencies.
For what it's worth, I recently heard a clinician say that he felt MLC would be listed in the DSM (Diagnostic Statistical Manual--used for diagnoses by psychologists/psychiatrists) the next time they come out with a new edition. It would likely fall into a depressive disorder, but any validation that it exists would be great.
