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

17 year old guy from Britain here. Time for some backstory.

So yesterday evening I was feeling rather unwell. When I say "rather unwell" I mean waking up at 2am to wander round my house in a fumbling mess. After about ten minutes of walking into walls, i'd go back to sleep and wait for the same thing to happen about half an hour later.

Jump to this morning, I have a single 40 minute lesson today in which I need to put the final touches on and submit some English coursework. This lesson starts at about quarter to two, so in a similar fashion to the previous night I spend my time coughing up my lungs in the corner of my room. As the lesson draws closer I drag myself into some clothes and stumble down the road for a 30 minute bus journey to my school.

I manage to get into school without collapsing on the side of the road and start heading towards my lesson. I see my teacher and she asks "what are you doing here?"

This is where things take a turn for the worst.

I'm doing two different courses for English, so my lessons are split between two teachers. Me being oblivious to this in my sickly daze, has come into school for the wrong English lesson.

At this point i'm pretty irritated, so I wander into my actual lesson. I'd rather not have wasted my time coming all the way here so I tell myself "it's only 40 minutes, might as well sit through it".

Bad idea.

Lesson starts off alright, relatively standard. Although my insides feel like a paddle boat in a tsunami I manage to get about halfway through the lesson. But after another five minutes, everything started to go wrong. The situation went from me coughing an awful lot to vomiting all over the girl opposite me (who I kinda have a thing for). She's pretty distressed by the ungodly amount of shit that's graced her and everyone else is either screaming or cracking up. Teacher has a look of sheer horror on her face and tells me that "it would be best if I were to leave".

I'm now sitting on a bus typing this message. Lady friend is yet to reply to my apology text. I royally fucked up today.
<bot>: After spending the previous evening stumbling around like a budgie on a carousel as a result of illness, I go into school to submit coursework, realise I had a different lesson and proceed to vomit all over my crush.
