I'm not "after" anything. On those occasions when I cry, it's because I can't help crying. My T rarely even acknowledges the tears and never comforts me, beyond the comfort I get from him in general. He sits patiently and silently until I can speak again.

If someone offers sympathy, a touch, or some other kind of comfort, it can stop you from feeling the emotion. If your goal is to feel your emotions (whether you really want to or not), then comfort can be counterproductive.

On the other hand, I can almost always hold it together unless someone expresses sympathy. That's when I lose it.
