So far the quickest description I've found is here: http://www.artofredirection.com/Emotional-Anorexia.html

Basically, I guess, it's an extensive (maybe even obsessive) avoidance of emotional intimacy and/or situations that might force one to be emotionally intimate. Though it's not the same, it's similar to anorexia nervosa (AN) in that folks with AN restrict their consumption of food/nutrition, while someone who's emotionally anorexic restricts taking in emotional nurturance, etc.

I don't know. Maybe it's just a convenient metaphor/label for something lots of people experience. I'm just sort of curious since my T mentioned it. And I have some pretty specific patterns around it, so it's definitely something that's causing me issues that I need to work on.

Thanks for your replies, guys. Anyone else?
