I found this recently-published article, Children who are bullied suffer worse long-term mental health problems than those who are maltreated interesting. Here are some excerpts:
A new study published in The Lancet Psychiatry shows that children who have been bullied by peers suffer worse in the longer term than those who have been maltreated by adults.
The research is led by Professor Dieter Wolke from Warwick's Department of Psychology and Warwick Medical School. The study is due to be presented at the Pediatric Academic Societies (PAS) annual meeting in San Diego on Tuesday 28 April.
[...] Professor Wolke said: "The mental health outcomes we were looking for included anxiety, depression or suicidal tendencies. Our results showed those who were bullied were more likely to suffer from mental health problems than those who were maltreated. Being both bullied and maltreated also increased the risk of overall mental health problems, anxiety and depression in both groups."
An abstract and full article (pdf) are available.

Poor social skills is more likely to indicate a kid at the younger end of the age range for the grade. For example, the kid who's birthday is just before the cutoff age for the school year. You seem really motivated to blame mental illness. Feeling guilty about something?

Sure, but there is a non insignificant number of people who have poor social skills (particularly when they are very pronounced) because of mental illness. We also see a lot of social skills out of the mentally gifted, who have signification higher risk of mental illness.
So the sample is not random, there will be more people with risk factors for mental illness than the general population. Not to mention that poor social skills can turn into mental illness all by themselves.
