For me depression is as a result of isolation. I'm not very social. Once you fell in this trap, both depression and isolation begins to feed each others, and it becomes harder to tell which causes which at that point. I just don't want to accept the virtual world as my reality. I've been like this for 6 years now. I'm not sure how the virtual world can push you out to the real world. Now I'm trying to socialize, it's not pleasant for me, but the virtual world isn't pleasant either.
