I just had the worst, most embarrasing day of school so far.

I went to school feeling great, but as I walked in, I noticed people disinfecting an area and heard 'Can someone get a sick bowl?'
Perrfect.
So, I went to my first lesson (science) feeling scared shitless that there was some kind of bug going around the school and that either I would get it, or somebody in my class would be sick because of it. I spent a few minutes outside the door, couldn't breathe very well, so I went to head back to the main area (I didn't want to go there, as someone had just been sick, but what could I do?)
However, as I made my way down the science corridor, I saw my head of year. He's the one who normally takes me to my lessons if i'm anxious so he knows me really well. He took me back to my science room, where I stood outside, shaking and crying with him for about ten minutes, before he told me I had to either go in or go home. I really didn't want to go home because I actually like school. I don't like going home.. So I stood at reception for a while, still crying (yeah, I was feeling like crying all day today. I don't normally cry), until my other head of year found me and spoke to me in private. I told him how I was feeling and he reassured me that there was no bug going around the school and that he would take me back to science if I wanted.
So I said okay. I spent the last 10 minutes of that period in the classroom, but it was too late to do work so the teacher just made me sit there.
Next lesson was english. I had to do a controlled assessment which meant writing a creative piece under exam conditions. I backed out of it, spent that lesson standing outside the door/sitting in the head of year office.
Third was English again, because it was a double period. My head of year took me, and the teacher told me that in the previous controlled assessment I did, I got an A*. I couldn't stop smiling, so I went in ^^
Then it was maths. I went in without a problem.
Last of all.. science again (oh yay). I went in feeling anxious. My anxiety got worse and worse and I pretty much had the worst panic attack I've ever had. I felt dizzy, like I was going to throw up, faint, collapse, I was shaking, pale (apparently), couldn't feel my legs, god the worst feeling came over me. I have no idea what it was.
Soo.. I ran. Literally. I just ran out of the classroom and all the way down the science corridor, no idea where I was going but I knew I had to get out of there. I was hyperventilating when I ran into my music teacher, who stopped me. Squished myself up against a wall (I generally do that when I'm scared), and she told me to breathe.. Slowly in, out. Eventually I calmed down enough to tell her where I'd been, and where I would go now. I've walked out of my music teacher's lesson before so she knows my situation.
As she let me go, I pretty much burst into tears and started hyperventilating again, and ran to the office where the nurse was. Without even asking, I just walked in and sat down on a chair, could hardly breathe and still felt like I was going to throw up. She managed to calm me down, and within five minutes I was ready to go back. I was still shaking and nervous but I just went back anyway. Apologized to my friends/teacher for running off and as it was time to go home anyway, packed up my stuff.
After the lesson, I felt like I was going to burst into tears, but I couldn't really do that at home, so I went back up to the head of year office, sat down and starting crying. Obviously both of my head of years were suddenly concerned about me, but they were saying 'Ooh don't beat yourself up about it, you did well today,'. They have no ****ING idea how embarassed and scared I was. They just sent me off.

Day/rant over.
Thanks if you read it all. I really need support right now because I feel like it's all getting too much.
