My T would uncross his legs, sit forward a little and quietly say "do you feel you can tell me what you are thinking & feeling right now at this moment?"
Then he would give me a few moments and if I didn't answer, he would say " the last time we spoke (blank) was happening, has something happened since then? His eyes would look more & more concerned. Then he would say my name a couple of times to make sure I was present. Sometimes I disassociate and he makes sure I'm present by softly saying my name till I look him in the eye.
Your question and the way you have asked it are making me feel concerned about you.
