If you dont let your feelings out - then you are not getting anything out of therapy. Scream, yell, cry, punch - do what you feel. You go to therapy because you DO have feelings and if you were managing them on your own, you would not need a therapist. Not being mean - being honest. He can only help you with your feelings if you share them. Therapists can only work off what we give them -they do not have a looking glass to get into our heads - we have to share what we think and feel in order for them to help us. You may have to ease into it, but if you dont share your feelings, how can he help you with them?
