I have a similar experience regarding my initial diagnosis; trust me you are not alone in this struggle. When I was initially put on Concerta, I was taking 15 mg and felt like it wasn’t helping as much as I thought, then I went up to 30 mg and also felt overwhelmed, on edge, anxiety filled, whatever. The solution is to talk to your doctor and work with him/her as much as possible. I also have problems with anxiety and talking to other people about topics like this, but you’ll feel so much better once you find a treatment that works for you. Try out different dosages, or even different brands of medication, if it isn’t working, tell your doctor, I’m sure they want to work with you to help find an effective solution.
Hope this helps!
