Is this a problem?

This is a long story, so I'm cutting out details to make it shorter. I graduate in a month, and I got started a little early on the job hunt. The rational part of me realizes that many of my online applications are most likely getting rejected because I can't click the "currently licensed" button. The irrational part of me is wondering if maybe it is something else.

It took me several years from graduation of high school to get to this point. My family experienced a very severe emergency that forced me to drop out of college. I still had a mountain of tuition debt, ensuring that I would not be able to go back to school for quite some time (they wouldn't release my transcripts until I paid them). I was young and barely old enough to drink. I thought I was fortunate to get a job as a teller at a Fortune 500 bank. It started out so great, I even saw a future there. But the recession happened. I don't want to make any excuses, but it was emotionally draining. As I said, I was barely old enough to drink. I was accused of ruining lives. I was screamed at by adults twenty, thirty, forty years older than me, who had lost their entire life savings that they had been accumulating since before I was even born. They told me that I had ruined their lives and their children's lives. I ruined weddings. I ruined Christmas. They HATED me. I could see it in their eyes when they looked me dead in the face and named me personally as the reason why they lost all their money. This was a daily thing. When I went home and turned on the TV, I saw news stories about people committing suicide over the economic disaster my workplace institution had caused. I was always a self-confident, sort of sheltered, young adult. Experiencing this left me with intense anxiety. Even though I knew the recession wasn't actually my personal fault, and I wasn't actually solely responsible for ruining lives and weddings and marriages, it still got in my head. I don't like to cause people angst like that, and I don't like to feel like I'm part of something that is causing people to suffer. It got so bad, I started messing up. I could not keep up with the company's demand to make sales, because it was impossible to sell to people when your institution was a major driving factor behind their misery. I made one too many errors, and I was let go. After the fact, I struggled with severe anxiety. I'm older now, and better. I still have anxiety, but I've worked in the food industry ever since and I've learned how to adapt and cope with high stress situations.

I don't like to make excuses, so the only thing I can say about it was that I was very young and it was a very intense time. On my applications, I do tell the truth that I was let go from this job. This job was almost eight years ago. I note that I was let go due to an inability to fulfill position requirements. I don't know what else to say. I'm not going to lie, because I'm sure they have a way to find out. But I also don't want to really draw a lot of attention to it.

Am I doing this right? Could this be hurting me? Should I just not say anything at all? It was so long ago. I'm a totally different person now. I love nursing. I've never had a bad review from any nurse or professor I've worked with. My patients have always loved me. I love my patients. My anxiety still troubles me in certain situations, but I've mellowed out and I can definitely work through it. This was one rough patch in my life, and I just don't want it to come back to haunt me.

Of course, I might just be over-thinking it. I just started my final rotation in a unit I love but does not hire new grads. I spent the first week getting to know my preceptors. Now I'm going to spend the next week finding a way to connect with the nurse recruiter and really emphasis how much I love the hospital, and that I would love to work on a unit that does hire new grads. I see a long future with this place, so I'm going to try really hard. In the meantime, this little rough patch on my application still kind of nags at me.

Thanks for the advice!
