Haier, You sound very scared and uncomfortable in her new office. You feel anxious there, like you cannot exit easily, your heart is beating....These are your honest feelings, very valid, and not stupid at all.

Your T would probably be glad to hear how you are truly feeling. You are helping her getting to know you better, so that she is more able to help you.

You are not complicated, you are interesting and a nice person to know. It's wonderful that you are aware of how you feel, when you feel ready you may want to share this with your T!
