<human>: I do not do drugs recreationally. Last night I took half a Tramadol (not sure of the mg) that I don't have a prescription for. I have back pain and can't seem to get a prescription for anything. I only take maybe 2 or 3 pain pills a year and this was due to moving a lot of heavy boxes recently. This morning I got called in for a random urine sample drug test. It had been 12 hours since I had taken the half pill and I always drink a lot of water. My sample was crystal clear in appearance. I'm mostly concerned about losing my job, but I'm also very worried about the shame and perception from family and coworkers if it comes back positive. I will at least be suspended without pay if that's the case and I don't have a good excuse (I ate poppy seeds doesn't count). Am I worrying over nothing? Or should I prepare for the worst? How should I respond if my employer confronts me about the results? I should hear something in 3-4 days if there's a problem. I can't believe this is happening. I feel like that little pill could wreck my life.

Can you succinctly summarize the text in 1-3 sentences?
