Hi Ed ~ I have about an equal number of good & bad days. Weather makes a big difference with me -- when the barometer moves, I'm in agony.

And in Michigan, that barometer is always moving! LOL
Have you tried Prozac as an antidepressant? That worked great for me for several years -- then I had to switch because it stopped working so well. We get accustomed to our meds sometimes, and they quit working. I'm now on Cymbalta 60mg twice a day. That seems to be working well.
I hope you find something that works for you. It's bad enough being in pain, let alone being depressed at the same time. God bless & take care. Hugs, Lee
