I forgot to do something at work- what should I do?

Welp, basically I forgot to do one of my closing jobs at work.

My day went along the lines of this- The person on the register by me couldn't find his iPhone. My manager had me look through my purse, and I found out my wallet was stolen. I called my dad and asked him if he could move the money from my bank account to one of his, then he and I eventually got into an argument about how I was getting home later. I went back to keep working, then the police found the guy so my coworker and I got our things back. We both had to write police reports. My wallet was all wonky when I got it back, but nothing was missing from it (I don't carry cash). I started feeling sick with a stomach ache pretty much right after that.

Later I did my closing jobs, and I forgot to do a couple of things. My mind was on figuring out how to get a different debit card, my stomach ache, and how I was going to get home. Today was just awful. It was totally my fault, but I don't know what to do. Should I talk to my supervisor and say I'm sorry? Or should I just wait and see if she'll notice? I feel so bad. It wasn't some super big thing, but I still forgot.

Yes by all means talk to your supervisor and say I'm sorry & explain.

If it wasn't super important I wouldn't even worry about it unless they confront you about it. And if they do, just explain that you weren't having the greatest day, and apologize.

You seem much more mature and responsible if you apologize to your supervisor, if you just ignore and they figure it out later, they will be twice as mad.
