No curling up under the covers, doesn't help. I know you probably can't hear it but the higher ups probably aren't as unhappy as you feel/see they are because of your depression and concerns about other things. I've mistaken concern for pissed too many times so you'd think I'd know the difference; sure they wish you'd do stuff differently but they're also hoping you will! If they wanted to get rid of you, if you're job were that "easy" to fill, they would have done it by now?

That you have other things going on in your life; don't pick a fight with what you enjoy doing and are normally good at! It can work out.
