The common language of depression involves beliefs that everything is bad, experiences confirm that nothing will improve, and patterns of guilt, grief, and anhedonia.

“This is the common language of depression. If this is very depressing to hear me talk about it, it is heavy. And that's what it's like to hear these things, it is even heavier, of course, for somebody to experience them. And those beliefs, those patterns of guilt and grief and anhedonia and delusional anti self confabulation, those are the things that eventually, if they get severe enough, start to convert into things like self harm mutilation, and in the most tragic of cases, of course, suicide.”
