I'm sorry that you're experiencing these problems. I always have issues with attention, and when I'm depressed, I cannot remember anything without a lot of effort. Once, when I was really stressed last year, my vision got blurry and I could not comprehend anything I read. I thought I was having a stroke, but thankfully, whatever it was, it had disappeared by morning.

I have never been on an antidepressant, so perhaps that may explain why your issues have been more intense. If so, I hope that decreasing the effexor helps.
