Welcome to the club of those who suffer from addiction. I do have one piece of advice for you. We all went through some of what you are going through. Remember that the courts are about punishment and Nurse diversion is about public safety - neither is really invested in your recovery so don't get confused about what's important here. The most important thing right now is building a strong foundation for your recovery. I totally understand the need to work but many of us were not allowed to work for close to a year. In some states you can collect disability under a dx of depression. If not you can get work in any field outside of nursing so you can make ends meet while you get that strong foundation I mentioned earlier.
You nursing career is not over just on hold for a bit. Anything you put before your sobriety is exactly what you will lose if you lose your sobriety. Who put you on suboxone? If you have been sober for a while you should consider weaning off it. It's really bad for your liver anyway. However I know many boards require it to help in deterring future use. You might have who ever prescribed it talk to your Case worker and explain the purpose and uses of this drug.
The thing to remember with the boards is what they really want to see is that when they yank the leash how fast you come to heel. As you build your recovery program this pill gets easier to swallow.
Also be careful what you eat and drink - become a conscientious label reader and avoid anything with any amount of alcohol in it. Check out the list posted at the etg website or at MEDfriends-in-recovery. Remember too that you are not alone. Get a sponsor and start working those steps. Great things will come to pass for you and countless others. I will keep you in my daily meditations.
Peace and Namaste
