"If I get......"
OK, that implies that you didn't actually try this stunt yet. Obviously you are desperate, or you wouldn't even be thinking about this. The problem is that even if you win by trying this stunt, you STILL LOSE! You don't think that's true, but I promise you it is. You have a gambling problem, and winning one big bet is NOT going to solve your problems. You WILL be right back in this same situation in the very near future, and if it's not this time, it'll be the next time that you will go completely broke.
I know that 3,000 in the bank isn't enough to solve your problems, but if you go through with this, you will curse the day that you p*ssed 3K down the toilet. Get some help, man.
