What is the definition of a psychiatric disability?

I looked it up, but can’t seem to find a clear answer.
Which of these would be considered a psychiatric disability?
-Clinical Depression
-Anxiety
-Rapid Cycling Bipolar Disorder
-”Psychotic Depression”
-Body Dysmorphic Disorder
-Borderline Personality Disorder

Any of them could be a disability but it depends entirely on how severe they are. It all depends on how badly it interferes with the person’s life. There are different degrees of disability and some people may function despite their “disability” while others may not.
