Anger is a secondary emotion that tells us when we have been hurt/had something taken from us. Just saying, "I feel angry," without elaborating on what you feel angry about so the other person can engage with you and either help you resolve the problem you are angry about or confirm that you have reason to be angry and may want to think of how to protect yourself from problems like "this" in the future, cannot help much?

When you feel angry at your T's response, right then say, "Whenever you say (whatever T said, quote it), I feel like you are not telling the truth/you are not speaking in a way I can understand/you are minimizing my pain (whatever you feel is going on) and that makes me angry. I feel like either lashing out or shutting down. (whatever you feel like doing -- yelling and screaming?)"

Anger is an expression of a problem and your tone/expression of it tells the other person it is important to you and they should stop everything and attend/work with you on this. The response you get from the other person helps you decide what to do next. Hopefully the other person helps you clear up any misunderstandings or elaborates on their response so you understand where they are coming from and agree that is a valid place and/or your perception was wrong, etc. or perhaps the other person does not care or cannot help you and then you know you need a plan to address the problem you are having on your own. If you are at a job for a long time, for example, and another person who has been there a shorter period of time gets the raise/promotion, etc. then you go talk to management about why you were overlooked and then decide to correct problems they may have pointed out in your work or go get more education like the person they promoted had, or change jobs because they aren't the sort of management you wish to work for (promoted by favoritism alone), etc. Just "being" angry or yelling and screaming at someone can't solve the underlying problem. Both sides have to work together or the side that is angry (the side which has a problem, which is why they are angry) has to figure out "Plan B" for themselves so "next time" there isn't a problem in "this" spot again. In other words, you don't keep letting yourself get "beat up" and angry about it, you "do" something. If the other person can't/won't help you then you have to leave them or have them thrown in jail, etc.
