Well, if the question is, is it OK to lash out at our Ts and be nasty and not nice to them - I'd have to say, no. It's no more OK really to do that to them than it is to do to our friends or family who care and want to help. That said, is it OK to show/express anger, negative feelings, and do it in a more respectful, controlled way in therapy, yes! There's no sense in bottling up our feelings/emotions about how things T said or did affected us.....better to be honest and open about it, to simply say it. And better to say something than just act it out, say with being late, or doing a lot of eye-rolling, or whatever. Like deli said, therapy is the perfect place to practice our communication skills, our relationship skills and learn how to do better at expressing our emotions and dealing with our feelings and situations in real life.......and our Ts should be ones who are safe to learn and to practice these skills with, so that we do better with our real life situations and relationships.
