My flatmate thinks I'm living with depression, I think it's anxiety (based mostly on the symptoms of "I really want to puke and can practically feel my adrenaline spikes').
Given that the recommended treatments are largely the same, at least since benzodiazepines fell out of fashion, and that I managed to work most days and see friends and keep on top of the laundry, it's not obvious that the diagnostic label matters much!
We've got to the stage where the labels have such complications that they don't really communicate what the symptoms or issues are, what treatment is needed, or what might be causing the problem.
Do you have a label? Is it useful to you?
