Crying is also a form of communication. You say you're crying and so you can't answer or continue a discussion, but crying is a form of expression and your tears probably say more than your words would. It is meaningful that you are crying in the presence of another person. Something my therapist asks that is useful sometimes is, "What are your tears saying? If you could put words to those tears, what would they say?"

I see no reason to be concerned about crying a lot in therapy. Crying in therapy is totally normal. Even crying *a LOT.* It's an intimate act and a good thing.
