Maybe you can try not to say anything that's not true in your sessions, so don't say "I'm not sure" or "I don't know" if you really do know. And just sit in the silence for a while instead of rushing to fill it with phrases that aren't true. Sometimes we need a little space and time to spit these things out, and most therapists are comfortable with some silence and won't rush to fill it themselves. They'll be patient and let you fill it, in your own time.

Good luck.
