I'm glad the replies helped you. I am still wondering why you went to therapy in the first place. I would think that reason is a place to start. You say you give one-word answers to your T. Are you willing to show her what you write in your journal, or can you write something that tells her why you came to therapy? I used to have a lot of trouble talking to my first T, years ago, and often I would bring in something and read it, or just give it to her. I also wrote poetry and gave it to my Ts to explain my feelings. You can be brief. Just write a list of what you want the T to help you with. Are you depressed? Unhappy? Lonely? Have trouble with relationships?
Do you like this T? Do you feel comfortable with her? Maybe you could do something other than talking in your session. Artwork maybe? My T had me do a collage about my Mom and I didn't have to talk much, though now I usually don't shut up in therapy.

If you can't talk, maybe you can draw a picture or make a collage at home to show your T what is bothering you.
I hope that your next session goes well, suzzie.
