Drug test anxiety

I took a urine drug test June 2 at 9am and still haven’t got the results. I was testing negative on at home tests but it was faint. It was like 40 days no smoking before the test, I wasn’t smoking too heavy. I’m on Xanax and adderall so it’s going to come back positive for that, but they have my prescription list. Could this be the reason it’s taking so long? I’m terrified. I’m never smoking again after this. The anxiety isn’t worth it. The test is with labcorp. I’m supposed to start job June 15th. Please help!!!
