You should be terrified; that was a pretty silly thing to do. Not that I haven't made mistakes in my life but I am always amazed with people who are terrified AFTER they get caught. $5k of theft would be grand larceny in Virginia. As you can see it carries 1-20 years!
Now, if you have no record, I would get together as much of that $5k as fast as I can and beg the mercy of the court for your truly boneheaded act (and you better tell them you consider it boneheaded) and offer to pay all or as much as you can in restitution as SOON AS POSSIBLE. You will probably still get 5 or 10 years in prison but the eager restitution offer will probably get most if not all of the time suspended for a probationary period.
They MAY, and I do mean MAY, consider giving you a first offender program if you qualify. If you get out of this without jail time, you better go home, hug your kids and thank GOD for protecting you when you did something dumb.
Sorry to come down on you so hard but I practiced law in VA and they are no joke. I get especially tweaked when someone comes in "terrified" AFTER stealing with impunity. Afterwards isn't the time to be scared. Look at your kids; DO RIGHT or you won't see them grow up. Good luck. (What jurisdiction are you in? What judge?)
