I have the exact same problem. My T handles the situation with a very gentle disposition, and with lots of compassion. She knows and understands my struggles to talk. She has learned how to gently pull most stuff out of me. When she can't, she tells me it's ok and that we can try again when I am ready. She also reminds me that I've come a long way in talking since starting therapy over a year ago so it's nice to be reminded of my progress. Never in a million years would she scold me or make me feel bad for not being able to talk. It's unfortunate your T treats you as such.
