Have you been on the medication for long? Sometimes the comedown gets a little more bearable with time. It’s definitely something to bring up with your doctor though because sometimes this calls for adjusting your dose.
I often get anxiety when my adderall wears off too.
A technique I use that helps the anxiety a little is to remind myself that I am feeling that way because my meds are wearing off, and that I will feel better soon. Being able to recognize the anxiety as just a side effect helps make it more bearable for me.
Switching to extended release can also help with the comedown. Extended release is a lot more mind but is also much more consistent throughout the day.
