Your comment made me recall some of how I felt on SSRIs. I went on SSRIs for several months for anxiety. My subjective experience of it was that the thoughts and obsessions that were continually going in my mind increasingly felt like they were coming through a fog and from farther away. Which was great in some ways because I could just enjoy being, but I need to access that obsessive mindset for work as a developer and for my personal projects that I care about. A lot of the time I felt like I just didn't care about stuff that I really should care about. If things were objectively going to hell, I didn't think I would be able to tell, because it kind of silenced or dampened the critical thinking part of my mind. So ultimately I decided to stop... occasionally I want to go back for the serenity it gave me, but I value my critical faculties higher.
