For me, it also means that I have trouble attaching any ideas with emotions. Even sad ones. Oddly enough, I can feel physical emotions like the physical depression symptoms of my stomach in knots, oh my head feeling like it's weighed down, of my face being pressed down forced to frown. When I take dopamine inhibiting drugs, whether prescribed (Wellbutrin) or something like caffeine, all I feel is alert. When it comes to sex I can physical physical pleasure down there but nothing in my head, not a hint of euphoria, not even mildly. Nor can I feel love, a book, not even music. I wrote my pdoc a letter. I plan on giving it to her soon, and we'll move forward with a treatment plan. Not many recover from negative symptoms though.
