Not sure what drove his decision, but he had certainly disclosed a lot of detail about his challenging personal situation in his posts. In my opinion it was a wise decision to remove them and let that published persona disappear.
Perhaps. I saw details that closely reminded of myself a decade and a bit ago, when I was really in a bad place, not having started cognitive-behavioural therapy yet. Very, very close similarities, although my problems stem from my work history and lack of work-life balance.
I have been open about my own history, exactly because a large part of my problems was that I did not know how to speak about them, or even
how to seek help. My problems didn't/coudn't fester, but they certainly ground me down during the years. Yet, having issues with depression and burnout is really no different than having a broken leg: in most cases, you can heal and become strong enough to not suffer anymore, even if you'll have some lingering effects like a twinge whenever the weather changes. Some disagree, but they're wrong.
(I agree to removing the personal posts possibly being wise, simply because many people are stupid, and revealing
anything about oneself makes one a possible target for stupid people. I have considered that myself, and decided that the positive effects (of maybe helping someone consider checking if they need help) are much bigger for myself than the risk of being targeted by stupid people. I already get targeted by stupid people for all sorts of reasons anyway, down to the choice of a mascot, one more isn't a big deal. So, the best decision will definitely vary from person to person.)
