I talk to people on fb all the time but nobody wants to talk to me this includes my old school mates and family I moved to tenerife for 4 years but in the 3 years I've been back home they don't talk to me or ask me to go places

Perhaps they don't like to chat or talk on face book, I don't, I almost never answer anyone back if they PM me on Facebook. That is not what I do on Facebook.
Perhaps they don't like you, sorry but not everyone likes everyone.

You make new friends, find people with the same hobbies, same political view points and so on.
