Your boss sounds like a good soul. Many bosses are soulless.

I've lost many jobs over the years; my positions having been eliminated and therefore me with them. Like you, my depression hasn't helped matters; I've been off twice on STD and have called in sick hundreds of times over the years, even today. I am sorry you'd lost your job, it is such a blow to oneself on so many levels. Do what you need to do to take care of you right now. And please be kind to yourself, something I find very hard to do.
