> You cannot necessarily just "figure out why" you feel bad

Well, of course, if you anesthetize someone they can't feel anything. If you cut off the physical pathways of ""feeling sad"" then they can't feel sad, but is that really the same as "fixing" the reason for why they were feeling sad in the first place?

Unless the reason was that the physical causes are running haywire and making someone feel sad when they otherwise wouldn't, but how often is that just uhh a lazy scapegoat? "Oh this person has no reason to feel sad, something must be wrong in their brain"
