Failed drug test, I don't do illegal drugs

I was taking 1 hulk tablet a day, the big ones. Would take half in morning half at lunch break. Lost my job and my car is turned off cuz missed a week of payment. Really needed this job I was going to get because am flat broke, and feeling withdraw on top of everything cuz last money I had went to phone bill.

TLDR

I took a mouth swab drug test for Express employment, failed for opi/amp/coc. I did drink a rhino rush shot maybe an hour before walked to the job site.

This really messed my life up because if I don't get job like ASAP I'm going to lose my car. I'm beyond depressed and hopeless right now.
