I've been in this situation before. I think the pre session email can help if it's possible. I wasn't able to do that at the time I had this concern. What I did do was acknowledge how I felt (nervous anxious, embarrassed, or whatever emotion I felt) and I know its ok to feel this way. I want so help with this so I feel less anxious, nervous, etc.

I haven't felt any judgement from my T since realizing I was judging myself (and punishing/self sabotaging). I am a harsher critic of myself than anyone else is. And anyone who treats me too harshly is not worth my time or energy.

Good luck. A deep breath can help too.
