I wrote this as soon as I had calmed down because I feared that I wouldn't remember how I felt, also it was originally written In swedish, I translated most of it with google translate 👍: 

"I felt like a balloon being blown up and up and up and up from the time I put on my shoes until M tried to talk to me. I felt like with every passing second I was getting closer to exploding and I didn't know when. I went outside and then all the feelings came like someone released the balloon for a while and let it blow air out and it kind of couldn't stop until it was all out. But the balloon is not gone. Its still there and the anxiety it will come back every time I go back to school."
