lost and scared

Hi, I am so scared from yesterday. I knew the day was gonna come, but didn't know when. I recently suffered an ankle injury with has result in multiple superficial achilles tendon tears. One night I was in so much pain and had vicodin left over from some back pain, and I just started taking them. I don't know how many I took, I just kept taking them until the pain had decreased enough for me to fall asleep. It was the middle of the night and I was desperate. And of course my number was picked to drop the same day. I know this is a HUGE mistake and I feel absolutely terrible about it. I am already in a recovery program through HPRP in michigan. My case worker was the one that called me about my positive drug screen yesterday. I immediately lied about it (being caught off guard was not fun). I now have to go meet with my addictionist today at 5pm and confess. This doctor can be very judgemental. I am scared I am going to loose my management job. I almost had 2 years of sobriety. Since HPRP was bought out, the people that work there are very strict. I know other people that relapsed and they just got additional therapy sessions, and 6 months added to their contract, and a narcotic restriction reinstated. Which is fine, since I don't pass narcotics being in management. That would be the best case scenario. Worst case, they report me to the state board, then I will probably have a perminate mark on my license. 5pm can not come soon enough so my fate can be decided. But in the meantime, I have to put a smile on my face, hide my anxiety, and put a smile on my face. Not easy.
