There are no consequences until you are convicted or plead guilty.
If that happens, or when it happens, you'll pay a stiff fine, more fees, court costs, be sentenced to probation and deferred adjudication, pay more money to the county probation office, do 40-80 hours of community service, you could be subjected to random drug tests, unannounced home inspections, and if you survive; the matter should be dismissed.
The counties in Texas no longer provide public defenders in most of these cases. However, you'll learn more about that when you appear.
At that appearance you plead not guilty, make no statements you'll be given more directions, another hearing date will be set, and you wait. Whatever you o don't plead guilty, don't blab, don't get in any additional trouble. This is your ONE mulligan. Don't blow it.
