Granite, I think it's important that you tell your therapist that you think she was angry with you. Then she can have a chance to explain her reaction and if she was angry or not. I think there have been times before you thought your T was angry at you, but it turned out she actually wasn't. Could that be the case this time? If she wasn't angry but yet you thought she was, this will help her know what about her reaction made you think she was angry. And it could help you know too that when T is a certain way, it doesn't necessarily mean anger. On the other hand, if she was angry, this will be a good discussion too. I think you will both learn a lot.
