I'm so sorry. This really sounds like it was his problem, not yours. A therapist raising his voice at at a client seems so completely unacceptable. You did do the right thing, but that doesn't mean that you don't still care about him or that you don't still want him to care about you. Unfortunately I doubt there is any way to make yourself stop hurting. I'd try to keep validating for yourself that it makes perfect sense that this hurts and keep reminding yourself that you did the right thing. And keep asking for support and validation here. People here do understand how a therapy relationship can be traumatic.
