Yes, and the other stuff that didn't work is most of the time SSRI. Treatment resistant depression is not a class of depression like bipolar or psychotic. It can be any depression that resisted the given treatment - that does not mean that the previous diagnosis was wrong. Exactly like when you diagnose a particular cancer and the the treatment does not work. It's still the same cancer. It has not morphed into something else, it has not jumped to a different type of cell. It just means your treatment options are limited and in this case they didn't work.
