I forgot to mention a few things:

* I found this app absurdly effective. Only used it like 3 times but it had a big impact: https://wuju.app/

* Square breathing helps. Inhale four seconds, hold four seconds, exhale four seconds, hold four seconds, repeat. Can do it as two second instead of four as well. Especially helpful if you feel stress.

* Pay attention for stress signs and process them. When I had some burnout it was like my stress response was oversensitive. So noticing I felt stress and either processing it (e..g someone cuts you off, you feel tension —> “They merely walked in front of me, relax, that is not a threat”) or using the breathing technique can help retrain your stress response.

Good luck! It does get better, just takes time and good habits.

Also random thing that helped once: consciously blowing off everything non essential and diving deep into Hades for a couple weeks. I think it was being totally focussed on a thing, and having a sense of progress, that helped.

Would not recommend as first step. Take care of small irritants and get good habits first. But then just totally letting go to some fun hobby can be an important part of the cure. For me it was Hades. For others it could be woodworking or pottery, whatever tends to immerse you.
