I am considered ro bw a really pretty girl but I dont know how to talk to people what do I do?

Im pretty and I think people dont talk to me because I look mean or intimidating. I also dont know how to talk to people or start conversations. I will go all day without talking to someone if nobody starts a conversation with me first. I even sometimes dont talk to my own friends for a few days just because I dont want to bother them. How do I get more comfortable talking to people in general. And flirting is an entirely different ball game. I have no idea how to flirt whatsoever. I usually just stand there and look cute and hope the guy I like comes up to me. I have no idea what to say to a guy if I like him. My biggest concern is that I might just be bothering people by talking to them. I even used to ask my own boyfriend if it was bothering him when I talked to him. Ever since we broke up I have no clue how to get talk to people. My ex was the easiest guy to talk to because somehow, even though Im shy as all get out, he might never know just how shy I really am because we clicked so fast that dating was easy because he was easy to talk to. As for other guys... I have no idea how to talk to them at all.
