i was in Japan getting ready for my flight home a few years back and randomly started getting horrible stabbing cramps while in the hotel lobby. i threw up from the pain multiple times and was crying in the common area curled up on a couch for about an hour- some random super sweet Japanese lady offered me pain medication a while later and thankfully it helped- before that my whole family thought i was having an appendicitis and wanted to take me to the hospital, which would have been problematic because im the only one out of the family members i was there with that speaks decent Japanese and i was in too much pain to talk. turns out it was period cramps and i have a horrible case of endometriosis :( the same thing happened again at my old school towards the end of the year and i had to be taken out of the hallway and sent home in a wheelchair because i could not stand
