So sorry to hear about your loss....

I don't really feel qualified to give you any advice, but I think we all have down times in our lives that we must weather. The good thing is that everything is temporary. The weather will change (not just in terms of the outside temperature).

Luckily, you have an overall good situation at work. And you have family who loves you (which I've deduced from your past postings).

Be good to yourself.
