<human>: Can you condense the text into a few key points?

So today I fucked up by accidentally changing my sleeper coach back 6 days instead of forward one, and only realising while waiting for the coach that never was.

I was supposed to be sleeping peacefully on a coach from Perth, Scotland, arriving in London with time to go home, get my laptop, and head to work. Now importantly, I can't under any circumstances miss this day of work. We are doing an installation and I, as luck and poor managerial decisions would have it, am the only one trained to set up part of the project.

Anyway, I only realise my mistake when the coach fails to turn up after 1 hour. I'm kicking and cursing myself for my abject stupidity. How the fuck could I do this to myself, and how the fuck am I supposed to get home on time now? 

I start looking into any and every option. I've got to somehow do a 9 hour journey in less than 8 hours. Oh, did I mention I've got 14% battery as I was planning on chareging on the coach. By absolute sheer luck I find I can get an internal flight from Edinburgh to London Heathrow at 6:35am for £71. ThankfulIy my provisional driving licence has always been in my wallet so it's okay I don't have my passport with me. I then find a taxi from Perth to Edinburgh for another £71. The cost of the coach I fucked up by booking the wrong date? £5. 

All this will get me home and into work on time. The only problem is I only get 1:30 minutes of sleep. It's a long and boring TIFU, but I've got nothing else to do while I wait for my call to board. I fucked up, I'm an idiot, and I'm dealing with it at cost.
<bot>: fucked up a booking, realise too late. Pay a lot of money so I don't fuck up work project - tired as shit.
