I Was Going to Tell My Coworkers But.. After How They Treated Me Why Bother

I got in trouble for someone else' error. As I was in the process of correcting that person's error she complained to my boss. I brought cupcakes and was going to send a cute email to everyone. But now, after crying all morning, all I want to do is put the cupcakes in the trash and not tell a soul. Not like they care.
