Mbo - stop, take a few deep breaths, and figure out why you don't want to go. The studying is a valid reason for not going (and admirable), the rest are bullshit. It looks like you don't want to go (subconciously?) for some reason and came up with all those excuses on why you shouldn't. And most of those seem rooted in fear.
Having been in your exact position not too many years ago (and many times since), I did what you seem to be doing and wussed out. I have since regretted that many times.
I would like to suggest that you figure out the real reason you don't want to meet MMario, and once you recognize it, decide if you still want to stay home or not. Don't let everyone bully you into going (because then you might resent going) but at least be honest with yourself on why you don't want to go.
Good luck.
