Hello, I've Recently Been Put On Probation For A Non-drug

Hello,
I've recently been put on probation for a non-drug related offense. However, I am drug tested and will continue to be for awhile. I am a University student and have taken Adderall without a prescription as it has helped me tremendously over the years. I have never been tested for Adderall, but I believe I fit the criteria for prescription. In addition, my probation officer recommended I get a prescription in order to continue its' use, otherwise it will be considered a violation of probation if I tested positive for it without a prescription. I was wondering how to become prescribed for Adderall or Vyvanse. Also, my probation doesn't allow me to drink alcohol and I have been getting bad headaches at night and have had trouble sleeping. This probation has driven my anxiety through the roof.
