<human>: Could you distill the essence of the text into 1-3 sentences?

So i do all nighters quite regularly because sleep is boring. I usually feel quite sick the next day but it goes away after a bit. 

So I have to travel back to college for a repeat exam (study kids). The bus leaves my town at 7 am so I thought I may as well just stay up then sleep on the bus. Big mistake. 

I had some cereal before I left, weetabixs to be precise. Within 5 minutes of getting on the bus I knew shit was going to go down. I've gotten this bus easily 100+ times and never been sick but this time was different. 

So I realise I'm going to be sick. Being an awkward loser stops me from going and asking the bus driver to stop. So instead I vomit into my backpack (I'm staying the night, laptop, change of clothes etc inside).

The bus is fairly quiet at this stage so no one notices. It happens roughly 6-7 times. My bag is now soaked in vomit. 

Fast forward. Bus journey finally comes to an end (praise the lord no one sat next to me). Now I have to get a train to my college. I plan on sorting my bag out once I get to my accommodation. 

This is where it gets even worse. Walk past and a security guard through the ticket barrier and he calls me back. "Excuse me sir, what is in your bag". I fucked up again here. I panicked and lied, I was to embarrassed to tell him. "Sorry sir but I will have to search your bag, we can't take any risks". At this stage we've attracted a big crowd because there's only one ticket barrier. He opens it, immediately vomits himself.  

Everyone is staring at me, people are horrified. I eventually get on the train and make it to my accommodation. Worst day ever.
<bot>: Was sick on bus into my bag. Bag got searched at train station by a guard. Security guard then vomited.
