This probably won't matter, given your state of mind, but I personally prefer to go to functions alone because: I can leave when I want; I don't have to be concerned about making sure the other person is enjoying him/herself; I won't feel like apologizing if the person says something inappropriate (I wouldn't have to anyway, but I would FEEL like I needed to); the other person wouldn't have to apologize for MY idiot behavior; I won't be exposed if I forget someone's name ("Steve, let me introduce you to my close friend and co-worker, ahhhh, ummm, sorry, I forgot your name."...happens to me all the time; I won't have to white-knuckle the drive to the function if the other person is a terrible driver; if I don't like the hors d'oeuvres, I can dispose of them discreetly; I can move around from group to group quickly without explaining why I'm bored to tears... Well, you get it.
