Anyone saying to not talk to people is probably a lonely basement creep; you don't want to listen to their advice. 
If you want to talk to someone, just do it. Human civilization is literally built on communication, it is totally natural. I used to be really bad at talking until I just realized how boring it is not talking to people.
