What made me wonder if my personality had just changed was that I wasn't my usual depressed self. The complete opposite. I was doing all kinds of chores and being ultra productive as if I was a completely different person. Then I started thinking about how I felt, and I felt like a different person. A completely different vibe. In fact even my nose senses feels different. Kind of like the same effect when if I or someone squeeze the tip of my nose. That kind of a sensation. Like a chemically indescribable sensation. It sounds very weird and it is.
