This is real progress. You did well to explore these past experiences with your current T, who is clearly engaged and open-minded and likely would be receptive to hearing how you recently approached a crisis line.

Personally I'm working on a topic to tell my T, how she scared me by reminding me of someone in my past. (Nothing she did, just her appearance and then turns out she'd lived once in the same city where my incident occurred although at a different time. Ick ick) But she's already disappointed with me for a much smaller reticence on my part. I mentioned last week that she annoyed me months ago in a chance remark of hers, and she was clearly upset I hadn't expressed my feelings at that time. I felt like s*** leaving that session.

All this is to say you have a really good T who apparently isn't counter transferred or arrogant or anything else that would close doors to your progress. So good luck in your future sessions, wherever they take you. You seem really smart and brave in all this.
