Hey there, i understand that you might be frustrated about not getting the best drug for ADHD, because you are born here.
Before that please try to understand that every country has different norms, and it's not like Adderall is the best drug available, for some people it doesn't work at all, and it comes with a very high abuse potential. When a doctor prescribes medication, they choose the best available medication.
Next Steps
Please trust them, and if you have any issues you can contact the psychiatrist.
