The ones you're really speaking about don't come up very much if discussing mobility aids and other situations, not on the threads at least across the years. The vast majority are more about someone viewing a mobility aid with a pre-conceived perception and then when it's suggested to use it (by posters or by Disney) get affronted. For sure there are times where having a mobility aid (outside of anxiety) isn't the solution to use 100% of the time but it doesn't mean it can't be used some of the time. There's nothing that says if you have a cane you have to use it all the time, or a wheelchair or an
ecv; as needed is perfectly fine too.
Individuals I know with anxiety including my cousin's child with cognitive disorder most avoid the parks
because of what the parks represent. They will not put themselves in that situation and I don't know anyone who willingly does so unless they know they can handle it on their own (like my cousin's child who has very much improved over the years; she knows her limitations as she's gotten older much better). Several combat veterans I know would never go to a theme park because it would trigger their PTSD (which is a question that has come up every now and then on threads). The ones I know whose anxiety is very debilitating are not about putting themselves in a situations where they will get triggered. My friend has high anxiety towards thunderstorms and unfortunately that is commonplace here but she does what she can mostly a weighted blanket.
I know you view the Parks as your place to go to get away from the rest of the world but it's not something the people I know with such high anxiety view it as, it's like their worst nightmare and they aren't compromising their mental health to go there. They don't go to our regional park either (except for my cousin's child with the cognitive disorder).
People deal with anxiety disorders differently and there are different triggers but you (general you) also have to have an understanding what a place can actually do for you or if you're a minor child with anxiety your parent or guardian would have to understand if you're choosing to go to a place that may potentially trigger you in some way or another including what options they have available for someone.
