I dealt with a really bad case of anxiety earlier this year. I was having the anxiety when I was both on and off my medication (I take generic Concerta), so that’s when I knew it wasn’t caused by the medication. That’s why in my previous comment I recommended going some time without taking the Adderall XR and see if you have the anxiety when you are off your medication. I was prescribed clonazepam for anxiety, and my anxiety levels are at a normal level now since I started taking clonazepam.
