Feeing/"being" and thinking are all inside and only coming from you. Whatever the feelings and thoughts are, they just "are" they are not right or wrong, good or bad, and they cannot be controlled because they are coming up from your unconscious or pre-conscious and you can't "get" to them to control them fast enough. But they are good things! They let you know what is going on with you, what you are thinking and feeling. However, there is an "about" that is necessary. You feel about, you think about a subject, item, interaction (with self or others; coming up from inside you or having happened outside you).

Talking and "exploding" are actions. First you want to get hold of what your thoughts and feelings are and put them into words in your head and only then do you decide, what action to take. Actions are usually decisions, unless you have an impulse control or neurological debility such as Tourette Syndrome. But everyone has to learn how to get thoughts and feelings understood inside before taking action (and to learn to take action, just just stew in one's thoughts and feelings!) and what sorts of actions are helpful to take.

I would not worry about exploding, especially if you or your parts have never physically exploded and hurt anyone? I think if the angry parts wanted to literally hurt someone, they would have done that by now. If you have been able to keep them from doing that or they have not wanted to go that far, have only thought about it and expressed it (I use to very much want to smash my fist down my stepmother's throat, but would never do that and never did) I would let go some and let them tell T how they feel, what they are thinking, who they are.

Pay attention to them! Listen to them and take them seriously. When we are listened to without censure, criticism, an angry response, we learn to listen back and get out what is troubling us so it is not so pent up anymore. An angry person/part notices when they are listened to and taken seriously. Too, when I'm angry and listened to I often find myself agreed with, that I have "reason" to be angry. That is calming, being heard and understood. A lot of anger and its "angry" expression is about that, trying to be heard. Sometimes we learn bad habits and take out our having not been heard in the past on a current person that does not apply in "this" situation; that's violence. Someone smashing their fist through a wall, putting physical expression to their thoughts and feelings is just showing they do not accept their anger, do not understand its purpose and maybe feel hopeless about ever being heard.

T will listen and I think even your angry parts will recognize that?
