Can an PSG outside of my NCO support channel direct me to disclose my behavioral health concerns/information?

Basically, there is an NCO who was my platoon sergeant for about 4 days. In this time period, I suffered from a behavioral health crisis-- which I could have absolutely managed on my own.

I explained how this was a personal issue, and one that I did not want to disclose.

The NCO in question effectively gaslit me into telling him. The NCO told me how he wasn't able to help me without knowing what it was, this is a day after he recommended me for UCMJ as he thought I was lying to him. I showed him evidence that I was not and he withdrew the recommendation.

This next day he apologized and tried to help me. Scared, doing my best to hold back tears, and worried that I would lose the dream job I worked hard for-- I told him I was scared to talk about my behavioral health crisis.

He promised me that it would remain between the two of us, and that he just wanted to know so that he could help me. I told him. He gave me some kind words. Two days later everyone in the unit knew and I was being referred to behavioral health services by my command and removed from the training I was in.

After this, I was transferred back to my original platoon. Despite that, this NCO still acts as if he is my platoon sergeant. He had his squad leaders inspect my room randomly, he has gone out of his way to get his own personal accountability of me even when I've already reported to my actual NCO.

Now, he wants me to relay what the garrison behavioral health services tell me when I go to see them.

I already feel wrong trust his rank regardless of his person-- despite how much I want to trust my leadership. He says he's just trying to help me but I'm genuinely scared this is just another plot of his and that this is all a facade to achieve his own personal agenda.

I'd especially rather just keep my personal health matters between me and my chain of command.

I just don't know what to do... It's not like I can just go up to him and say "SSG, you lied to me and now I can't trust you" and I also can't say "SSG, I don't have to tell you about my personal health situation"

Moreover I don't want to say any of that. I want to respect him because I respect the rank, but is my only option here really to just do what he says when it's about my personal crisis?

Thanks everyone for reading and helping. I know there's a right answer here, I just don't know what it is
