No, it really isn't a good idea to base your theories of psychiatric medicine on a satirical half-hour cartoon show about swearing construction-paper children.
It is true that there are some corners of the internet where probably-healthy people meet to discuss what it's like to have disorders that they probably don't have, or in some cases disorders that might not even exist.
But you really ought to talk to some actual doctors and patients before you conclude that their problems aren't real, or can be overcome by pretending they don't exist.
South Park is poking fun at the industry, but it's humor. It doesn't tell you what the problem is. I only mentioned it because it's a good related episode :)
My point is not about pretending problems don't exist. It's about focusing on encouraging people rather than focusing on claiming who they are.
