I Spilled Coffee All Over My Boss's Laptop

Yesterday was one of those days where everything just went wrong. I woke up late, hit every red light on the way to work, and then spilled my coffee on my keyboard. I had planned a huge presentation for this week, and now my laptop is ruined. Took me about 15 minutes to finally calm down enough to realize my backup was at home, so instead of presenting it today, I would need to copy all the slides from there. Decided to just stay late after everyone left and use a spare keyboard at work to try copying them over. But then...I walked out of the kitchenette with my coffee and right into my boss's office. She was talking on her phone but put it down as I stumbled in, spilling hot coffee all over her brand-new MacBook Pro. It wasn't even unplugged or anything; she just had everything spread out across her desk. The silence afterward felt like hours long. My boss just stared at me with this shocked expression before finally asking if I was okay. 'I-I'm fine, but...' Trying to explain what happened made things worse somehow. The whole office could probably hear my voice cracking through the door as I apologized over and over. Now she's letting me off easy by not firing me immediately - just saying we need to talk tomorrow about how this will be handled. But all I can think about is how bad of a coworker I am for making such a huge mess after already ruining my own laptop in the morning. Did I ruin any chances of ever working here again? Am I being overly dramatic? Or should I start polishing up my resume just in case?
