For me: accepting I have "down" days. And trying to never push during those days. Put breaks, read a book (not related to work, not reading it to be better at anything because thats work as well), go out, exercise. Learning to say no. Not overengineering things (because thats a time sink and I have to throw away 2/3 of the prototypes I'm making anyway). Freeing weekends (or free days). Taking time to talk to people about things not work related. Reduced the "arguing because someone is wrong" (on the internet or not) helped as well, it takes a LOT of emotional energy.
I forgot! Reducing caffeine from coffee and using tea instead when I feel stress is increasing or when I didnt sleep well (thats the worst time to drink coffee for me as it starts a tiredness and anxiety circle that may last a few days). This reduced my anxiety a lot. And I also noticed that coffee increase my procrastination. Not sure why but I would likely put that on increased anxiety.
