Texas Board, please help

I am really scared. I was granted a conditional liscense in FEB. 2006 due to some issues when I was 18 years old (i am 26 now).

To make a long story short my probation period was 24 months, so I quit calling in to my random drug test center on the 2 year anniversary. APPERNETLY some of my forms were mailed back late so my probationary period was extended through July (making it a total of 30 months

THE PROBLEM: I missed a random drug screen in early May because I was never notified my probationary period would be extended for late quarterly reports submited by my employer.

Are they going to take my license for a missed drug test? I have a wife who is 6 weeks pregnant and a 7 yo daughter. I made a big mistake by following the 24 month time frame on the paperwork and not clearing it with the case manager.

I am calling in now, and my case manager said any missed screen "will count against you" when I told her I had not been calling in. I'm not sure she knows I missed it, but I know, and I am scared.

Anyone ever been in a situation like this with Texas and recieve any positive or negative resolution? I am human and I made a mistake, I have never tested positive for anything with them ever.
