I have had exposure therapy for fears and phobias. What your t is doing sounds like "emotional flooding" which is a controversial way of dealing with a phobia. It means you force your way though overwhelming anxiety and supposedly you end up on the other side of it. My long term t though that flooding was just asking for retraumatization Most of my t's have worked with me via gradual exposure or as one t put it stress inoculation. All gradual. If t asked me to do homework and it was too much then next time he would break it down into more manageable parts. How experienced is your t anyways?
