My question involves criminal law for the state of: Texas

I am a first time offender. I just recently got on probation for possession and I have my first probation meet 1 day before my flight to europe and right after the probation meet I will go and meet with my judge so she can meet my mother because I am only 18 and i went to court alone. I have to go to Europe because my grandma is sick and I am going to be gone for a month and a half. What are my chances of being allowed to go? Ticket already bough
