I forgot my insulin at home

Shit right? Anyone else ever done that? I work 9 to 5 and I’ve got two meals during then. I’ll avoid snacks to keep safe but im worried about meals. I order lunch the day before and I’m getting a burger and fries today. Think this would throw me over the edge blood sugar wise? Think I’ll make it until 5? How long can I last with high blood sugar. Not asking for medical advice just ranting.
