I've had depression and anxiety nearly my whole life and the only medication that really changed my anxiety is Atavan. I've been on buspar, clonazepam along with several different antidepressants.
When I was younger(in my 20s) I got into the wrong hands and been put on Adderall and even Ritalin to drown out the anxiety! Didn't work, it was awful.
I distinctly remember the instant miracle it felt like when I started Atavan.
I could function. I could sleep better. It made therapy and trauma work much easier to get through.
Everyone is different but for me it was a game changer.
When I'm doing better I take less and vice versa.
I hope you find relief because I know how horrible anxiety can be.
I would combine with cbt or some type of therapy or mindfulness to keep adding to your tools to manage.
