On balance there were few sessions with former T in which I didn't cry, whether just welling up or full on sobbing. Having grown up in a "I'll give you something to cry about" environment, experiencing that my tears were acceptable was important. And since I burst into tears early in the very first session, I was able to experience that acceptance before there could be any ambivalence about crying. I suspect the immediacy and intensity of that emotional interaction had a lot to do with establishing such a strong bond between us.
But my T only addressed the crying directly in that first session. I think part of the acceptance for me was in not drawing attention to it thereafter. So I wonder if your T making any comment at all about the crying has brushed against some earlier sense/judgment/shame? Could the lingering feeling be from something forgotten or displaced?
