I was prescribed some medication time ago, and it felt me the most depressed person, but I was aware that this must be the cause of it, and asked my doctor to stop it. The other medication was not that effective, as this one, but I no longer had the moods. I was feeling as if nothing really matter, but this time literally, not in some "grand scheme of things" way. I had to push myself somehow to do things. It could've been something else, but it coincided and stopped days after I started taking that medication.
