Help me figure this out.

Hello.

I am dealing with issues regarding my medication. I take Adderall XR 30MG. I tend to take it everyday but on a day I feel like the medication isn’t working and my mind continues perseverating and being irrational on certain actions from the past, I can tell it isn’t working like before. So, I think that I’ve hit a tolerance point in my medication, but I’m not sure how I can lower/reset the tolerance to my medication.

What is this? Anxiety?
