Anxiety attack in front of my students

So today, we started a new unit for a novel and my first period felt like a disaster. For some reason I felt an enormous source of panic because my co-op didn’t post the activity on the class site so I had to go running to make copies for 30 kids. After, I could see we were running alittle behind and I was getting nervous. I’m a new teacher and I do have anxiety. As we were going over the lesson for the intro and preface, I could feel even more stress and my thoughts and ideas were all over the place. I could feel an anxiety attack and I was trying to hide it but I was so flustered and a mess.My students looked confused with what was going on and I was trying so hard to answer all their questions but my emotions and anxiety took over. I felt like such an idiot and I felt my students thought I didn’t know what I was talking about. Tomorrow, i want to apologize to them for what had happened and explain that i had an anxiety attack, but is that a good idea to be that vocal about an issue I’ve had all my life?
