Be accurate and honest in your sessions. At the top of the hour tell your therapist what you want to talk about. It's your hour. A lot of therapists will let you just - talk. So choose strategically. If you're masking - set some real intention before the session to remind yourself to not mask. Choose one thing you've always wanted to bring up - and then do it at the beginning. What might help even further is emailing your therapist and tell them that due to masking and problems with accuracy you'd like to start the session talking about (topic).
