I am so sorry that you are going through this. Please don't lose hope.
Have you been tested for Lupus?
Also, have you tried Pristiq? Just because you've tried Effexor does not mean Pristiq won't work. The stuff worked for me for a long time when nothing else did. I had to go off of it last year because it finally wore off after several years. Thankfully, Cymbalta is working pretty well.
You might give it a try.
