Well, I have yelled at my therapist a couple times and yelled in general several others. I'm not proud of it, but she didn't leave me, she didn't really seem too fazed, actually, and she accepted my subsequent apology with very good grace. It is hard to control anger for some of us, I mean, it's the primary issue that brought me to therapy, and she knew that going in, so... I think it's a lot to expect for that anger to never manifest imperfectly.

However, what I have found more fulfilling in terms of my anger when words weren't really enough was physical acting out. My therapist says anger is energy that needs release and she encourages clients to do that. She's even given me some examples of how she's done that. I, for example, find it really catharctic (and pretty harmless) to take a steel pipe I had handy from the basement and demolish a bunch of cardboard boxes.

I'd tried smashing glass too, which some recommend (or plates) but managed to cut myself. I actually found the boxes even more satisfying: you might try letting your anger out in some physical way, whether it's breaking things, exercising, using a punching bag, etc.

Nothing wrong with anger, the only issue is how we channel it.
