Is it OK to get angry in therapy?

The fact is that any good, well trained therapist is able to tolerate and accept those times when there is anger or disapproval directed at them. When that happens it is helpful for the patient because they learn healthier ways to not only express their negative feelings but to experience feeling acceptable even so.
