It just aggravates the sox off me when people make those sweeping statements re "Not Believing In" MI or things like autism. My favourite thus far is "Oh he's just being difficult/lazy" (said in regard to my now-adult Aspie son). O RLY ?!
I get very snarky, unfortunately: climb way up on my high horse and ask sthg like "Oh indeed? Do you believe in diabetes? Heart disease? High blood pressure? Cancer?" I'm relentless!

Grrrrr! Conditions that have the power to skreww up our lives and indeed end them, all require treatment & intervention. ALL. Ostrich syndrome is neither helpful nor useful. My late husband was a big denier of many, many mental & emotional conditions -- until he got a couple. Suddenly he was on more meds than I was, going to a neuro-psych every week, eating Klonopin like candy....The world changed, believe me. And, 15 yrs late, I got a heartfelt apology. He was a good man and I loved him, but he had this one blind spot...and until it happened to him, he couldn't "believe" in it. I used to call him "Prince of Egypt" -- bc he Lived By De Nile lol.

there's really no use imo trying to educate folk like this. You've given them good information, and you've taken your well-being into your own hands. Well done!
