Thank you. I like how you started it "I used to be bi-polar". After being diagnosed with bipolar I turned to zen buddhism, and after a year of being diagnosed I learned to let the "label" go. Still, can't deny I suffer (like now) or have highs, but not where near as before.
I agree, I won't say anything unless critical, this is was not only for me but to show how difficult is to manage this personally, for the company and we as tech industry, since burnouts are frequent and depends on a lot of factors. Each person reacting different.
I have made many of your lifestyle changes. Definitely rebooting my brain with buddhism and stoicism is still key to control my self. Playing piano is another.
But right now the thing I need the most is to turn off the computer and iPhone for 1 week and get lost in nature.
