I don't know about your therapist but my counselor has admitted that she sometimes trys to make me mad on purpose. She says thats what a councelors job is - making people face their problems and feelings and when she notices that I am avoiding something thats what she targets and sometimes her target is agner especially if she sees I am not expressing anger even though I say Im mad. She does that because I have what she calls lack of affect - cant express my emotions and her making me mad in therapy is supposed to break down that lack of affect wall by showing me that its ok to get angry in appropiate ways.
