I think those articles are stupid. I dunno, maybe they help people who aren't really suicidal and do not actually want to die, but as someone who has considered suicide since childhood, a "self-care box" and "you're just having a bad day, it'll get better!" just isn't helpful. At all.
As for the corona situation, I think everyday life is better like this. Much less pressure on being normal and expectations to participate in stuff, people keep their distance, and I feel more free than I have in years. If my future wasn't so glum I would have enjoyed this (except for people actually getting sick and dying, as well as financial issues, but as a pure egoistical view point of the situation).
