How does one handle overwhelming "bad" stress?

By bad stress, I mean thee type that causes a lot of negativity in your life with no positives (unlike say getting a promotion).

The details don’t matter, but I have a lot of it right now, and I can’t do much to rid myself of it for the time being (though hopefully in the next few months). I constantly feel on edge, and overwhelmed, and I wonder if perhaps I could be handling it better. I am able to calm down, but then some new bad stress rears its head and I’m in even worse shape than before.

The one thing that does help me bear it is throwing myself into cooking, but as I cook for just myself there’s only so much time I can spend doing that.
