I think there's a difference between being mentally unhealthy and being unhappy. You can be mentally unhealthy and with access to proper medical care you find happiness. Or you can be totally mentally healthy and you can be unhappy for other reasons. Also, people with more money have much better access to mental health care.

I agree. There are beautiful people who feel lonely. And it is much harder for them to find people who would love them not for their looks.
There are funny people who feel lonely. It’s much harder to find people who love them not for their sense of humor.
There are people with great personalities who feel lonely. It's much harder to find people who love them not for their personalities. Let us take a moment to weep for them.
