When you say "mental illness", which disorders are you specifically refering to?

After reading the mental illness threads of the past couple of days, I get the feeling that when most jellies use the term “mental illness”, they’re referring to some very specific mental disorders, not the full spectrum of disorders. Are you guys referring to bipolar, depression, schizophrenia, but not learning disabilities or ADHD? Major depression, but not dysthymia? Mood and personality disorders, but not sleep disorders? Help me out here; when you talk about mental illness, just which ones are you talking about? Is there a certain level of severity you’re including in there that may not encompass everyone who’s been given that diagnosis?

Here is a list of all the disorders should you need it for reference.
