In Mexico and freaking out

I keep getting in my head about accidentally drinking bad water. I’m staying with a friend and I’m so nervous about getting sick and embarrassing myself. My panic attacks woke me up last night and I had to lay on the bathroom floor and take a zofran. So far I’ve only eaten a single taco and I’ve been here almost 24hrs now.

Anyone else have emetophobia and traveled to Mexico? I’m so nauseous right now and I can’t tell if it’s “real” or not. I’m also on my period, jet lagged, and am still getting used to the high elevation (CDMX). I’m so afraid my whole trip is going to be ruined and I’ll have to go to the hospital or something. Going to sleep is a huge trigger for me. Even when I fall asleep my body’s nausea will wake me up, and the fact that it woke me up will make me think it’s real, then I’ll really panic. Ugh!!! I just want to enjoy myself. I’m homesick
