I did something stupid

I'm overseas in for a week and had two sensors fail on me in two day. I know I should have packed more, but I did not. Trust me the guilt I feel is killing me. Luckily I have enough test strips but still. I haven't not used Dexcom in three years so I called them to see if they had any vendors here. They couldn't help either. Anyone know where I can get a sensor over here? I know Dexcom is everywhere!!! I'm currently in Paris with another couple of days in Barcelona. Thank you all!
