I empathize. Deeply. I’ve experienced severe anxiety as well, and very high stress due an environment where I felt powerless.
What saved me (in no particular order)
1. Sport. I felt I was “burning” my stress and anxiety by doing 1h of sport a day, in nature.
2. Therapy
3. Family and friends, quality time
4. Find another job
5. Stop social media
6. Fixed sleep schedule
