Whiner

In a week and a half I'm to pick my Leaving Certificate subject choices, which is basically A-Levels or SATs or whatever you want to call them.
Except the teachers who were explaining the subjects did a horrible job and I still don't know what to do.
I'm thinking of studying law, but I can't afford to put myself through a complete legal journey. I seriously can't, I NEED to move out of my parents house ASAP, they want to know everything and I just want to go out and drink with some friends and not get screamed at for it.
I'm thinking of taking a course in Limerick in 2 years, but I need a job, and I don't have a fucking clue and my career guidance counsellor just fucked off the next day when she was coming to my class, I can't see her until wednesday... with the 25 odd people in my class. HELP!
