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).
