Triggers at work

Currently, triggered from a work situation.
There was a situation between some members on the team. I go to my boss to notify him of unhealthy team dynamics. I of course end up being emotional and the whole conversation shifted from focusing on the team dynamic to my lack of emotional regulation.

Why are you reacting this way?
I have some feedback for you…
And the worst one:
I am concerned for your career if you cannot regulate.

While all true, it is extremely discouraging.
I can’t help feel the shame and disappointment creep in.
No one knows I have this secret, but I can’t help but feel like I’m slowly being exposed and I feel incredibly uncomfortable.

Little does he know but he is putting salt on my wound. My biggest insecurity is my emotions. And lack of regulation there of. Anyways, I needed to write it where people understood how heavy this secret can be.
