I've been on this rollercoaster for 20 years and I wish I had some words of wisdom to provide. The past few weeks have been pretty bad for me, too. For me it always comes back and I know that I always find my way out somehow. When I'm in the throes of my depression, it always feels like this is the ultimate bout that will send me over the edge but I always come out on the other side. This doesn't help me when I'm in the moment but if you can somehow make yourself believe that you will come out of this, maybe that will help. Hang in there is all I can say.
