Congratulations, Tom, on what looks like a good outcome for your errors. Thirty months will be over before you know it and you'll be back on your feet again in no time.
Advice - Go do something that you know how to do, or learn a trade. You'll have some time on your hands over the next year, so you might want to study something that will make you employable in the private sector. You could study something like landscape architecture, accounting or even civil engineering, where if you know that hot water's on the left and shit flows downhill, you're halfway there.
But stay away from the Karma of violent things - like weapons, wasps and nasty people. I hope that you find peace without having to keep your stories straight, or that your memory improves. Certainly you're learning the value of following the rules.
