You should have thought about this harder long before 17 days till DoomsDay. Selling something off or getting a loan of some sort is about all you have left at this point.
I've had my share of these things in my colored life, jail time can go quick but the usual Probation after is the real "this sux" part. Once they gain control of you in your day to day life, it becomes hard to live. You are at their mercy to jump through whatever hoops they think up even after sentencing. In getting Probation, you agree to whatever stipulations they can think up. Regardless of a "sentence", you agree to abide ny their recommendations/rules. They rely on you for their job, and they want to keep it, not help you. Good Luck Wake. Try to get the cash and get it over and done.
