I just got my first ticket. What am I going to do?

I am only 16 years old, and I got a speeding ticket in Texas. I was going 90 in a 65 MPH zone. I am scared because I am only on a provisional license, and I still restrictions. Also my brother in law was telling me that I can’t go to defensive driving classes because I was going 22 MPH over the speed limit. I am so scared right now, I don’t know what’s going to happen and if my license is gonna be suspended. Does anybody know what I can expect? Or what I should do? Anything!
