I know you said the honest truth is off the table... However, it's my opinion that the truth is the best. It's the number 1 priority in my therapy. Actually, it'swhy my last therapist and current therapist chose to work with me. Why are you scared about being honest?
As for what to do next... again my opinion is to find another T asap especially if you feel you'll need help. Even if the T is not "the one", they might be useful in the short-term. Ask your T for referrals.
When my ex-T abandoned me, I quickly sought another T because I knew I needed help especially keeping myself safe. First T didn't work out. Only saw her twice. Second T I didn't like at first. But I stuck it out with her because I couldn't seem to find anyone else. Overtime, our relationship grew, and she wound up being one of the best Ts I've ever had.
I wish you luck!
