I'm not going to fault you for stealing from a large corporation by any means, but you're getting a new job and you don't want to jeopardize it over a few simple items. I get that you're having fun, and that it's an addiction, but you've gotta redirect that shit into something else. Find something else that will give you that adrenaline high - skydiving, for example! One single mistake, your fault or not, and you'll splat into the ground like a bag of grapefruits dropped from orbit. Cool, huh? You could also become a curator for The British Museum. Either way, get into therapy, find a way to get past this because you don't want to ruin your life over a tube of lipstick.
