Some quick type 1 help please!

I’ve only been injecting insulin for about a month now, and I’m still getting used to things. I drove to work today without by bag, and now my meter and NovaLog are 30 miles away from me for the day!

Can/should I just eat a fatty/protein lunch without any carbs, if I can’t inject insulin? Or should I just skip the meal entirely? Or is this a bad enough situation where I should run to a close pharmacy, call my home pharmacy, and have them transfer the prescription?

Normal lunch time is in an hour, so any help is greatly appreciated!
