Is it normal, that i see the toilet, but can't make it?

It was a warm may day. I was in seventh grade, barely thirteen. I had gotten up really early because it was the last day of school. I was so excited, I forgot to use the bathroom before I left. I was in French and my teacher, Madam Courtirre, is so mean. I had drinken four sodas at lunch and had to pee a little. I decided to go before it got too serious. So, I raised my hand and asked, of course she said no! I thought 'Who cares? I don't even have to go that bad!'. After another two hours of French, I had to go really bad. She still wouldn't let me go. After the bell rang, I raced to the bathroom, but my friend, Kris, stopped me. He was a boy, so I couldn't tell him I had to pee! He talked to me for twenty minutes straight. By then, I was jumping up and down in my mind. He asked me to walk home. I did. He offered me a sprite, and since it was hot I drank it all. Half way home, I couldn't hold it! I ran ahead of him and tried to find a sheilding bush or tree! Finally, I did! I was about to strip, when KRIS CAME OVER TO ME! I was thinking, 'OMG! Just leave me already!'. He asked me what was wrong. I said nothing, and tried to run again, but he grabbed me! I finally shouted at him. He let go. I ran all the way to another bush, I began to squat, but then I saw a port-a-potty. I ran over to it, but peed along the way. Ad what was worse? Kris saw me! I was right in front of the toilet! Why couldn't I wait two seconds longer? I still have the same problem today. HELP ME!
