major depressive disorde
"The first day I tried Zoloft, I sat and looked out the window all day, watching it snow. All I could think of was how pretty it was. But it also made my heart beat VERY hard. I could feel my blood pounding through my head and neck harder than I'd ever felt before.  My doctor had me try smaller doses, but even at 25mg the same thing happened. So no Zoloft for me. Which is a shame, since it really did show promise."
