My T would ask you "where in your body do you feel those feelings" and then she'd have you do something to process them. That's somatic experiencing.

You say something triggers these feelings. I would think it's important to discuss what is the trigger, or have you already done that? You say it's in the NOW, but strong feelings about our T are usually not from the NOW, but from something in our life, past or present. Though I try to deny that when my T asks me when in my past did I feel anger, for example!

I think you have to keep bringing it up until you get it resolved. Sometimes our Ts just don't understand what we need until we tell them repeatedly, I guess.
