I would try to get up the courage to ask. My T encourages communication when ever a client needs... but most of his clients aren’t quite as needy as I am. We had talked about him preferring phone contact (I HATE) but that email was OK. A few months in he VERY uncomfortably brought up the emails and how he didn’t want to be punitive but that he couldn’t keep up. We had a really good discussion and I can still email as needed but he knows that unless I specifically ask then he doesn’t need to feel pressured to respond. But... part of my point in sharing is that it was just as uncomfortable for him to bring it up as it would have been for me to bring it up. T’s are human even if they don’t like to admit it.
