This attitude is what keeps people from being willing to seek help when they suffer from depression or suicidal thoughts for fear that skeptics will judge them as faking or lacking character. As someone who lived for over ten years with multiple undiagnosed mental disorders and suffered significant, unnecesary setbacks as a result, I believe we still have a ways to go before mental health is treated with the appropriate amount of concern.
That causes damage. Turning your ankle or pulling a muscle might be more obvious, because it's purely physical, but there isn't as much difference as you think.
There have been studies that show that long term unemployment causes permanent changes to a persons personality, one not easily healed by getting a new job[1]. These modifications to thinking and increased stress levels lead to physical changes (and argumentatively decay). Pointing out the source of the problem in society does not change the fact that it isn't mental illness. Quite on the contrary, giving a source is similar to pointing at a poisoned well and saying "That's why everyone is sick.", but then afterwards saying nobody is really sick because we all know the well is poisoned.

Try taking some social animal like a bonobo, and sticking it in a horrible cage in solitary confinement, and maybe poke it with a cattle prod now and then for extra measure. Do you think it's going to be a perfectly happy little ape? No, it's going to become morbidly depressed or disconnected from reality. There's nothing wrong with the bonobo; the problem is with his environment. The bonobo doesn't need anti-depressants, he needs to be put back into his healthy bonobo society in the forest and not kept in a cage and zapped with a cattle prod.
Most mental health treatments are just band-aids, just like dosing a tortured ape on anti-depressants so he doesn't have to deal with the suffering he's being forced to endure.
I couldn't even imagine going through such a process when I was at my worst. It wouldn't have happened unless someone physically forced me to do it. I actually would have ended up 'choosing' to be homeless (or dead) if it wasn't for the care of friends and family.
worse the system discourages not giving patients the designation they want because doctors are routinely subject to surveys that must come back positive, by the very patients they serve
this is not to say there are not people with mental disorders but the vagueness of some disorders leads to a lot of abuse and in some cases its because people figure they don't have to deal with it, life in general, its not their fault, its far easier to take that declaration of disorder and put the blame there and not change lifestyle, job, or habits.
The DSM has certainly done its share of damage, I have to say. I think we'd agree on that. I'm not even sure it's done more good than harm.
You keep coming back to this being a problem with our social structure, and honestly I do suspect it's probably the biggest factor. This is why I support Basic Income (with a non-ludicrous rollout, and plenty of balancing along the way).
The group is probably overrepresented in suicide stats too.
