thanks for all the advice guys, im so far leaning towards telling them, though i know they will definately freak, they are really against drugs,

ive applied for a job at a videostore, if i get it im gonna save up and move out into my own place asap, so itll be no longer necesary to tell them, if i dont get it, or dont get any other type of work i will probably have to tell them, they might kick me out for a few days, but they do need me, my mum needs me to do laundry, dishes, make beds and do alot of otherstuff she has trouble doing these days, and my dad needs me to help him do his accounting, type up his emails and organize his business, he cant afford to hire a pro to do all that coz theyd charge him way too much, so at most i might have to crash at a mates place for a few days before they call me to move back in...... theyd obviously demand me to quit but ill just take a stand and say no.....
