Feel awful after first marriage counselling session

My husband and I just had our first marriage counselling session. And I feel terrible afterwards. It's made me feel like everything I say is taken in a way I didn't mean, that he thinks that I think so little of him. I know that's part of therapy, learning each others perspectives so we can learn to communicate better. But I feel like im going to be on eggshells with every conversation now, like I don't know how to talk to him. I feel less close to him than I did before. Is that a bad sign? Shouldn't I feel positive about making changes and working towards improvement?
