Once a therapist, who was into depth psych, answered this type of question by saying "you can't dive all the time. You have to come up for air." At least in the type of therapy I do which is more long term, periods where it seems not much is happening are accepted as part of the process. Things deep down shift more slowly than you might think and that is probably still occurring even when you've shifted away from addressing it directly.

I use those times to develop either other things, like more routine things or to enjoy and strengthen the relationship. Since in psychoanalysis an ordinary chit chat type of conversation is marked as unusual, this in itself says that something different and probably helpful is going on. Normalizing and self-expression are also part of therapy.
