I (22f) am diagnosed with anxiety and working on it (meds + therapy). I am working at a short term job that is low effort and can be repetitive. Headphones isn't really an option, normally I listen to audiobooks or music to distract myself. 

I find myself having to work very hard on keeping my mind in check. I can normally do this okayish if life isn't too stressful, and this job isn't stressful. However because it is 8h+ every day, I get exhausted. I am practicing my mindfulness and am seeing results, but last time I was in this situation, I had a break down. Now I spend a lot of my time trying to redirect my thoughts and keep them from going into an anxiety ramble. (ie. I caught someone elses mistake and let the higher ups know. They told me it was a good thing I noticed and left. I then had to work very hard to keep my brain from going down a spiral of thinking he is angry at me).

I try to sing songs (mentally) or tell myself stories to keep my mind busy but I don't think it is enough. 

Does anyone have any tips or tricks? Something that works for them?
