Falling and I can't get up

So yesterday I had yet another chaotic day at work but I must say I do enjoy what I do. So I came in to work early anticipating another full day and boy was I right. Since I arrived so early I couldn't park in my usual spot, near the administration building, instead I parked near the plant itself since it is the only place to enter in so early. So blah, my day goes on and I really wanted to leave on time since I was going to get my hair done so at around 2:45 p.m. I get ready to go. I also knew that the shift at the plant ends at 3:00 p.m. so I wanted to be in my car by 2:55 p.m. and out of there before the mass exodus of people arrived. So I was quickly packing up and of course I should have started earlier because I get stopped by one of my colleagues, well, no biggie I will just need a few extra minutes now to get my car out of the crowd, whatever. So I begin walking to my car and all these people were coming out, just like a sea of tired workers ready to get home just as much as me I'm sure. So I casually walk over of course with my laptop in tow and I had heels on, go figure, I never wear heels. So of course I was a little slow and I didn't realize that I didn't need to swipe my badge card to get out and of course people are giving me dirty looks. So I keep on going and I step off the pavement and as soon as I do...I fall. Now I literally tumbled down, my shoes went flying, my purse, I had dirt all over me and the whole nine yards. So people start to split around me and as I gather myself up I am trying to walk backwards to get my shoes and people are like literally pushing me and like not letting me get through the crowd, note: I'm barefoot. So as quickly as I could get my shoes on I calmly got in my car and then started crying. I don't know if it was the fact that I was embarrassed or that the people look at me with some horrible stigma because I work in an office. I don't know. It doesn't matter to me if you work in an office or a plant or anywhere for that matter. I would treat everyone the same because I like to say I live by the golden rule. Am I perfect? No, of course not but I really could not imagine myself pushing someone who has just fallen and not even asking a quick "are you okay?"
