there's a lot of very online Discourse about self-diagnosis and medicalization and romanticization and various ways of over-identifying with your mental illness
but out in the real world there are just so many people who desperately need to hear that the thing they're experiencing has a fucking name and isn't an objective perception of a terrible reality or a shameful failure of moral fiber
however grating the Internet thinks it is to hear someone wax poetic about their triggers, you gotta understand, this is by far the most comfortable way to learn someone's triggers, compared to all the other ones
especially seeing as how reliable and trustworthy mental health care is already an expensive luxury in American society, and only likely to get worse, self-diagnosis seems more like a necessary survival skill every day ~Chara
