I was diagnosed with MG early 2022 and started with bulbar symptoms (slurring, choking, head dropping) and collapsing for no apparent reason in 2021. Even knowing what's going on, even with treatments that have helped (a bit), I still run into problems when I start slurring and stumbling - people just assume I'm intoxicated and rare pretty rude. In the moment I don't always realize why I'm being treated badly - unless I start stammering I don't know I've been mumbling. I have a wallet card about MG but the font is tiny. By the time someone has decided that I'm drunk and therefore being disruptive, they aren't necessarily willing to squint at my wallet card. At the times when I'm struggling with speech, I generally am also experiencing some of the fun "constellation of neurological symptoms" that is part of MG: not fatigue but feeling like I'm inside a kaleidoscope that someone is spinning. Frequently unable to put words together at all.
After a recent and very upsetting experience of this, I made up my own version of the wallet card, but in 11 pt Comic Sans (looks friendly) and have stashed some in my handbag. I haven't deployed it yet, but at least I created a self advocacy tool when feeling ok and now have it to use when I don't.
