How can I get over being so shy?

It's something that comes naturally, you can't force it out of yourself, but you also need to relax and try to loosen up and be a little more open. Take risks, of course safe risks like give yourself opportunities to speak in front of a large group, sing in front of a group of friends, meet new people and make small talk! it's all a part of the process but it will get better over time, trust me I know :D
