Frustration with Disability Fakers

I'm so angry at people who fake disabilities and or exaggerate stuff for attention. not only does it completely invalidate my actually disabilities it also has caused people to treat my disabilities like a joke because they think they can be switched off and on cos that's what the fakers can do. it is wrong in so many ways and the fact that I lost all my freind because of someone fakeing/exaggerating cos they made everyone think I was being cruel when I was just trying to educate them better as the stuff they were saying was inaccurate and invalidating (this was before u realised they were just attention seeking). it makes me feel like shit cos I dont wanna accuse someone as faking, but even if they werent they were using it for attention and spreading misinformation. this person the tried to shove me today, unprovoked, so yeah they're a bitch. so I'm really pissed. has anyone else experienced something like this?
