Is it hormones, or do I just suck?

How do you know what you're good at? Or what you could be good at? I mean, I know for sure I'm a decent singer, and that I can walk 5 dogs at once. And I'm pretty good in bed. Alas, I will not be taking part in the world's oldest profession, so that's out. 

This whole week I've made several stupid mistakes in terms of my job. It's not a hard job. It's downright boring at times. My coworkers go out of their way to make sure I don't do anything too difficult. I'm basically paid to act like a functioning adult on my boss' behalf. 

I also want to cry all the time. So, it might also be hormones. Like, a homeless person just came on the train and now I feel really bad for her even though she is obviously crazier than a bag of chocolate covered xanies and has commandeered 4 seats with her stuff. But she doesn't smell that bad, and she has some dried flowers in a cup in her shopping cart. 

And now I'm tearing up. 

Excuse me.
