>>11219316From my own personal experience though, I feel like I can get deeper into thought, almost a trance like state with one topic in focus when depressed. If I take SSRIs it doesn't happen anymore and I feel mentally overstimulated, but my energy and fatigue levels return to normal levels.
Depression is different for everyone. I've come to think of it more as thought patterns that don't quite jive with society rather than a mental illness.
