I do think you need to be assertive and tell your therapist how you feel. (coming from someone who is unassertive). My xT at first had a timer, and I had dreams of opening the door and throwing it as far as I could so he could never find it again. I felt like I was food that was being cooked. He ended up not using it anymore.

My point is, you are not alone in hating the timer. I do hope you will give it a few more sessions, and you can interview at the same time if you feel the need. Keep us posted!
