I'm sorry you're experiencing this. Yelling: almost everything I've read lists this as a red flag indicating a counter transference, burn out, or personal stress and recommends supervision. But, of course, in most cases supervision can't be mandated (in US) unless it's part of a ruling from a standards board. The defensiveness is a double bad sign because it indicates he wouldn't be open to any sort of mediation. So you don't have a lot of choices. Maybe, if you can, look around for another therapist. and if you really want to go back because you feel you could still make progress--not because you feel an attachment--then use the other therapist for consultation for awhile to protect yourself.
