Obviously none of us have any certainty of whether or not you'll go to prison, but, as others have said, you're doing yourself no favours by claiming all this was a 'mistake' you made.
It wasn't a mistake at all, you consistently stole from the public purse, it wasn't a 'one off" event (and that would be wrong enough) , you continued until you were caught.
You've said you wanted to be caught, which is why you didn't reconcile payments, but I wonder if people listening to your case will be questioning that statement. I'd be wondering if you deliberately didn't reconcile any payments because you wanted to 'muddy the waters' by mixing legitimate purchases amongst your fraudulent ones in case anyone looked into discrepancies, rather than you did it because you wanted to be caught.
I'd also be wondering why you didn't quit your job as soon as you knew you'd done wrong, and own up to your addiction, or if you couldn't own up, at least you'd have taken yourself away from temptation and the ability to continue to steal.
I'd be wondering if you were really remorseful only because you were found out, and I'd also wonder why you've only just registered with associations like Gamcare if you knew you had a gambling addiction, have you only done this for the benefit of the Court people might wonder ?
You've managed to get help before for gambling, people might also question why you didn't seek that same help again to help you quit, instead of using your position to fund your lifestyle. There's so many factors to take into account, but for your kids sake, I do hope you're not given jail time, but that you're made to pay every single penny you stole back.
