Can't tap into my brain

So, I think my emet started as young as 8. I was such an worrisome child I guess. Mom says I worried about everything. Well, before I knew I had emet or anxiety, I was experiencing anxiety symptoms. One of the first things that happens to me, is I get a kind of numbness in my cheeks/face area. I start to swallow a lot and my hands get tingly.
Somehow my 8 year old mind trained this to equal being nauseated.
Since that was what I feared, and caused my anxiety, I assumed that's what it was. I didn't know any different and since last time I vomited, I had anxiety symptoms after I just added them up.

So now I obviously know that is not nausea at all. It's 100% anxiety symptoms, I know and accept this as fact.

But, even though I know this I can't get my anxiety to stop. For two hours now I have felt "nauseated" which I'm really not at all!! It's like my mind has a mind of its own. lol

I'm not sure if this even makes sense, but my boyfriend and I are just curious as to why, even if I know it's not nausea, I still panic?

Is there some part of my brain I am just failing to tap into?
