Unsure what to do

I'm not even sure how to word this. But after my assessment for ODV (Outdoor vending, Magic Kingdom). I've discovered I'm just genuinely bad at my job. I have medical accomodations that I have recently submitted and I've sent various emails and had conversations with leaders about getting me moved to somewhere else in food and beverage. This job is very physically demanding. It's not bad at all!! I love it and it's fun! It's just super hard for my body to literally do. And I can't come home so exhausted I can't move for a day or two. Working multiple days in a row is a drag, I've almost collapsed a few times. All I've been told is that since I'm a DCP, there's nothing I can do about it because I accepted this role. But this is quite literally the only role in all the parks I cannot physically handle. I don't want to leave and go home, I love it here. But if I can't get moved out of ODV. I'm not sure I can physically last and stay.
