Hi ronf, I remember reading a lot of your posts. Sorry to hear you're feeling down, there aren't always words that can just wisk away the pain as you know. I understand how a big convergence of circumstances can bring on a type of depression that feeds on itself, I've been there. When I felt like that most advice seemed trite as it really changed nothing.
Prayer, faith, meditation, trying to keep busy, forcing myself to exercise. All the usual stuff helps but it takes time. Probably the worst thing to do is isolate when you're feeling down. Hang in there and stay strong, the universe turns as it will, we just get to go along for the ride.
