Failing to report is not helping your case. You may have options available to you, including defending against a false positive test or simply having an understanding judge make a judgment call, but failing to report is making you look worse. I know of some bleak outlooks which turned rosy.
It is certainly possible you may be revoked and sent to prison, but refusing to face it only makes prison more likely. Hire a good criminal defense attorney as soon as possible, listen to his/her advice, and face the situation.
You need to hire a lawyer to try to do some damage control. Chances are very, very high you will be revoked. (My only hesitation in saying that it is 100% is that you put Corpus as your home city.)
