Have you tried using "props?" I would "learn" to get a Kleenex from his box to hold, prime myself some like that? Or, something that allows you to cry by yourself/at home; bring that in, special "toy"/pillow or blanket, etc. I love being "comfortable"/safe so wore my bedroom slippers to therapy a couple times in the winter :-) and brought a favorite throw that had belonged to my grandmother to a session once.
