Why shouldnt loners and such gather in close proximity? Very detailed question...?

The entire point of being a loner is that you are either unacceptable by social standards or happen to have very little in common with what modern day society considers normal. Loners may not be the best word to use when describing people like myself (A schizophrenic, depressed insomniac). However, for lack of a more suitable word, I will now decide to use "Unique". Me being so very "Unique" has its perks and benefits, and I prefer to see it as a strength rather than a weakness. "It takes all types" I always say! The point of all of this is to ask, why don't people even slightly similar to me have somewhere to go when society rejects them? Should we not have someplace to congregate and talk? If so, where? Many people merely act and think themselves to be part of the unique subculture, which makes it harder for depressed and troubled people to find answers that will actually make sense.
