Iris,
I will agree with SG (something I find myself doing quite frequently
) that this is not a silly question at all.
The answer is most definitely no, and I know because if the answer was yes, I would have been kicked out of therapy YEARS, if not decades ago. I have been working with my present T for over four years individually (more like six or seven if you count the couples work before that overlapped with my individual work) and last week I had the 4th session EVER during which I did NOT cry.
I have at times, just sat and sobbed for long periods of time (I'm talking a solid 10-15 minutes of JUST crying, no words) when I have hit deep grief. I have spent huge chunks of sessions with my hands over my face, eyes closed, curled over a pillow crying coming up only for air or to blow my nose or choke something out. I seriously believe my T's Kleenex bill dropped substanially when i stopped coming as often.
My first therapist, bless her, when I was struggling with this very thing, told me that crying IS a form of communicating. I don't think you're having a Palovian response to your T at all. One of my Ts favorite sayings about therapy is that it's a safe enough place to feel scared. It's also a safe enough place to feel sad. I think you have reached a point where you trust your T not to leave you alone when you cry, to stay as you walk through your pain, to understand you as your express your feelings. All humans have a deep need to be heard and understood. If we did not have that, we will search until we find someone to listen and understand. And when we do, if we have searched for a long time, we have a huge backlog of things that need to be expressed.
I don't believe that everyone will have a need to cry a lot (my husband actually once asked our therapist if he was working hard enough because he wasn't crying like I did at the same time that I was sitting there convinced I was doing it "wrong" because I was crying so much.
Our T was VERY clear that both ways were ok.) but if you feel like crying, then cry. It's honest and it's a way to communicate. As far as relief goes, there probably is some, but you are also doing REALLY HARD work when you are allowing these feelings to emerge so it makes sense you'd be exhausted afterwards. I often am quite drained after a session.
The other thing to remember is that we learn how to soothe ourselves and regulate our emotions by being in the presence of an attuned other who is attuned and soothes us. We learn this implicitly by being in their presence, experiencing and feeling them do this for themselves and us. We literally build the neural networks that allow us to do this as we interact and grow. If we did not have an attuned other focused on our needs, then we lack those skills. So part of what is going on is that by allowing yourself to cry, and to feel in the presence of your T and having her stay calm and contain you, you are literally LEARNING how to handle these emotions on your own. It's at the heart of the healing process.
And learning to "be" was one of the greatest gift my T ever gave me, among a plethora of gifts.
And again, what SG said is true, just keep letting the feelings come and eventually you will start to find a narrative to explain what the feelings are about and what they say about you.
