Cameron McMillin, who lives near Sacramento, California, suffers with a condition called Ehler's Danlos Syndrome – a connective tissue condition that has resulted in the teen undergoing multiple dangerous surgeries.
Last week Cameron parked outside the Rocklin Elementary school and when she returned to her car she found an anonymous handwritten note pinned to her windscreen.
The college student took a photograph of the note and shared it on her Facebook page. It read; 'Ladies, it appears that you are both able bodied. It's disappointing to see the misuse of that disabled placard here at Rocklin elementary. Please reserve this spot for those who are truly less fortunate than you. Thank you.'
Upon finding the note, Cameron admitted that it made her cry, but instead of accepting the shaming, she decided to fight back, saying 'I think it's my turn to say something.'
'Hello. My name is Cameron McMillin. Today you made me cry, but that's okay. I'd like to take this time to inform you about a medical condition that I have called Ehler's Danlos Syndrome.'
Cameron wants to raise awareness and educate the public about her condition, which is relatively unknown; 'People who have Ehler's Danlos Syndrome are never heard and I want to change that. It's about time we gain a voice.'
Explaining to her parking-critic; 'You have no idea what I go through every single day. I know you made a snap judgment by what you saw, but what you see on the outside is not what exists on the inside. My body may be weak, but I am strong.'
Since it was first posted a couple of days ago, it has now been shared over 2000 times by people supporting Cameron's heartbreaking response.
Pamela Weaver Whitted said; 'I'm sorry it made you upset. It upsets me. I also have EDS. This sort of things happens often and it's so wrong.'
Stephanie Baker agreed: 'I have to tell you I get dirty looks all the time when I park there on my really bad days. EDS is tough and people have no idea. Thank you for being strong and saying what needs to be said.'
