Also: Look how HAPPY he was, in December, while celebrating his birthday. Also, his home appears to be in great order. My main question is: what *reason* was he given for not receiving promotion? At risk of stating the obvious, that seems key.
Again attempting to clear up misconceptions about mental health and suicide: you can feel as happy as you want in certain moments, but it doesn't seem to have an effect on following through with suicide or having depression and/or other mental health conditions. In any case, looking happy is easy. That's why you can go outside and not notice anyone is depressed, when about 10% of the people you're looking at suffer from severe or major depression.
