Elaborating, I think, rather than disagreeing: Self-treating into passable normalcy is basically life. One of the characteristics you have to have in order to be diagnosed with any psychological disorder is that it has to be interfering with your life. Absolutely everybody can read the DSM and find a good half-a-dozen things they may have tendencies towards, but if it's not interfering with your life, it's not a disease/diagnosis. Liking a clean space does not mean you're on the "OSD spectrum", being a bit nervous around spiders does not mean you're on the "phobia spectrum", etc.
"Healthy" isn't a single point in psych space, if for no other reason then that there isn't a "perfectly healthy" person available to define that point for us! It also certainly isn't a well-delineated boundary, but it is clearly not a single point, and even within the space of "healthy" there is clearly a lot of diversity.
Yes, and this is true of any mental issue. Hell, it's also true of physical ailments that don't leave obvious visible markers. Depressed? You don't seem depressed. Anxiety? You talk with people all the time. People don't always understand that this functioning is the result of a lot of invisible effort.
I'm sure that their are people out there that like to play the victim, but that doesn't mean that people's struggles aren't real.
Wow, you really hit the nail on the head with this. Just look at all the people here trying to second-guess my own self-assessment!
I actually think some people get attached to the idea of their victimhood and helplessness, and this can easily become a disincentive to making positive (and very difficult) change.
(Yes I know there is the other side of it which is real, that medical expertise can help too. But like everything else, oversimplifying into a clear binary of diagnosable vs not, is not always useful.)
