Good to hear you’re better, but it seems weird that your symptoms weren’t caught earlier. Even a very simple questionnaire like the MADRS has explicit sadness as only one dimension. You would have been asked for lack of initiative/procrastination, stress/anxiety and negative self-talk. Sounds like someone didn’t do their job properly (unless you hid your symptoms from your family doctor or didn’t go, of course).
When I just looked, similarweb had the data for June and they showed a drop in visits of 3.36% and a drop in rank. So something happened - but not much. And that may only reflect the temporary blackout in some subs.
