I don't know how new this therapist is for you, but for me I usually have to spend about 3 months or more just talking about nothing before I can tell a therapist anything important. Maybe that would help you get more comfortable if you don't try to pressure yourself to talk about something important. Just kind of talk about your world views, politics, religion. Or about your friends and what it means to be friends with someone. Anything that tell something about you without being too personal.

The only professional that ever helped me at all spend months just asking me about a video game I played whenever I would freeze up and get nervous. He would listen to me talk about my video game until I calmed down and then we would maybe talk about something about me for a minute and then more bs... He was really really patient. I think it would drive most therapists nuts, but perhaps that is why he was the only person I could ever work with. Now that he is gone I won't even go back to therapy.
