If I may chime in... yes, labeling matters but labeling is not the problem. It is rather the result of the present approach, which often lacks important components, to mental health education and training. Yes therapy and drugs help but only to a point. (Yes i have been on medication for 14 and in therapy for much longer than that).
I fear that labeling will continue as long as the mental health professionals and workers are trained to drug the patient and take them into rooms and have them talk for an hour about bad things that had happened to them.
This video does a better job explaining my thought process.
