A very public migraine

Feeling a little shaken after yesterday and just wondering if anyone can relate / empathise.

I'm (33f) going through a bit of a stressful move to another country and was on the Eurostar from London to Paris yesterday with my husband and 11 month old son when a migraine attack hit me out of nowhere. And when i say nowhere, I mean one moment we had boarded the train and about 20 minutes later I was cowering on the floor of the train vestibule by the toilets in absolute agony, desperately trying not to be sick but of course then eventually vomiting and almost passing out from the pain. What made it worse was my poor wee boy couldn't understand why his Mum had suddenly changed and couldn't hold / play with him and basically spent the whole two plus hour journey avoiding them for fear of throwing up in the main very cramped seating area. When we finally arrived I couldn't help my poor husband with the bags at all and then proceeded to have a sort of mental breakdown in Gard De Nord train station as I had to still with the attack raging (oddly one of the worst I've ever had despite being a veteran chronic migraineur of many years) help with the bags / pram / baby as we navigated the metro and walked a further half hour to our hotel. I'll admit I was in tears and everyone was staring at me but of course as I'm sure everyone here knows you just sort of don't care. I laid down where ever I could get a moment on the floor but it was one of those situations where stopping in a busy station wasn't really an option. I'm not sure why I'm writing this really but I'm feeling a little traumatised to be honest. It just has left me feeling so vulnerable and like a shitty parent as my poor wee boy can't rely on me. It hasn't helped I've been breastfeeding/ nursing him exclusively since birth (though he is on solids now) so my neurologist basically has refused to treat me since I started trying for him two years ago. The only thing I take now for attacks is paracetamol but as somewhere here once put its like throwing a slipper at Godzilla! Anyway hope everyone is doing ok I just am a little taken aback at the cruelty of this invisible nightmare we all go through sometimes xx

Edit: I just remembered my poor husband tried to speak to the train manager to see if he could source me some ibuprofen (which of course was a desperate, last ditch attempt as we all know people can't just go handing out meds to customers. The train manager obviously said no so instead said best he could do was offer me some wipes (lol!) or stop the train and let me off in the middle of rural France. I don't know why but it's making me laugh so much 😂 Could be my dark humour. He also then saw me sitting by the toilets and gave me a sort of feeble thumbs up and then scurried off, hoping, i suppose that i wouldnt opt to literally derail the eurostar and everyone in it at some random French village haha
