Not really from lack of progress or not doing assignments but I know I frustrate my T repeatedly. I can always tell because he lets out a long, loud exhale. It is his way of releasing stress. My brain is extremely stubborn and set in negative thinking. He has the patience of a saint but I know I frustrate him. The good thing is that he doesn't really blame me. He knows I am the way I am because of my past and it will take a long time and a lot of work to reboot my crazy brain.
