Great job on 16 days! That's terrific. I'm sorry you didn't pass the test. I hate when stuff like that happens. It's okay to be sad over it but if you know what didn't go right this time you will be that much more prepared for the next time. Drinking won't make it any easier or change the outcome. When I get that stressed sometimes I just cry and get it out. I come on here and read. I eat ice cream when I have an urge. It passes.
So hang in there. Well done on not surrendering.
