Um...
Why aren't you at your first ever NA meeting tonight, missy?
Quit f***ing around, this is your LIFE, girl. Try to get the car back, if the dude gives you any hassle, call the police and report it stolen, tell them you were in a bar and left the keys on the counter and went to the lil girls room, when you came back, the keys and car were gone. It's that simple, really. PUT YOURSELF AND YOUR RECOVERY FIRST. The only reason you are REALLY helping these people out is cause you don't wanna screw over your connection, and because deep down you still want to use. F**K 'the man', you need him outta your life completely ANYWAYS if you wanna get well, so stop doing him favors. You're just gonna end up using what he gives you and you damn well know it. STOP IT and get to some friggin meetings prior to your purported 'checking in', too, it'll do you some good I promise.
