Rather than look at it from a perspective of "right/wrong", "should/shouldn't", perhaps one could go with the concept that there was an unconscious "need" to bring something to the surface, to make conscious the need to find a new way to address feelings. All there is is lessons, as the well-known saying goes, and he's in one. By discussing it here, we all get to benefit (Thanks, Monica, for bringing it to the forum).
He has been taught to express his feelings honestly, which is important, but then what? For all intents and purposes, they were "what is" for him, and so he said so in a moment of intensity. "Ok, so this is 'what is'"... but perhaps he's now at a point in his life where it's time to figure out the next step; "what do we do about it?"
One of the first things that's revealed is that one can't actually "hide" from their feelings. He already knew, it seems, that he can't hide them from himself, thus the honest expression. But now he's seeing that he can't hide them from anyone else, either. Not really. Thinking we are hiding these feelings of conflict with life, we still end up creating painful experiences revealing our inner conflict. It's as if life took this opportunity to show him that: "Ok, this is 'what is' for you, but you can't hide it. That doesn't work."
And perhaps this experience has revealed to him that in this world at this stage, perhaps the best arena for emotional revelation is a very private one. A sort of symbolic pointer toward "within". That's where the feelings live or originate, that's where they need to be addressed: "Ok, so this is 'what is', but putting it 'out there' brings a whole new set of escalating emotional experience".
His action was a first step in taking responsibility for self. He "owned" the feelings by expressing them honestly. But how and where we do that matters, as this experience clearly shows. Second step is, once these types of feelings are revealed, "something" must be done about them. By choosing to express them "in the world", so to speak, we get one kind of result. Perhaps this unconsciously occurred out of a sense of "need" in him that "something be done" about what he's been feeling.
In our fears around fear, we tend to want to push them off on someone or something else. He's clearly been shown that this won't work to his advantage, either. "Perhaps if I blame my environment for my feelings, something will be done to change them both." But no, what he sees is a revealing truth that "out there" is not really the cause of what's felt "in here". And "out there" has no clue how to fix what we feel "in here". Out there is just triggering us. The real place of difficulty actually and truly is "in here".
What society chooses to do about fear and other feelings in its institutionalized insanity, he is now seeing is not such a satisfying response. It solves nothing, blows things up to proportions of ridiculous, and generally creates more havoc than the original feelings. "Out there" is actually a secondary causal field anyway. Trying to fix something there is bound to compound, rather than resolve, the problem.
This is the world he's currently living in. To get such a vivid display at such a tender age, while frighening, uncomfortable and unsettling, may be just the ticket to shake him awake to the need for a different kind of response to the emotional center in himself. A sort of jolt that says, "take personal, intimate responsibility for yourself". Anything else is just crazy these days (and always was, I'd say. It's just that now it's become impossible to deny).
Best to you, Monica, and your son,
Sowelu
