Don't be silly! You can't expect to change drastically from someone shy and quiet to a lively extrovert overnight! Any change will be gradual, but it's really good that you've seen some change, just focus on accepting who you are first, and then you can work to change it! My boyfriend is really shy and quiet, he finds it really hard to talk/think of stuff to talk about. He'll ring me, wanting to speak, but then he won't have anything to say! Luckily I talk enough for both of us, and I'm comfortable with silence too. You can focus on being more outgoing, just practice speaking to people, friends, I'm sure they'll help you. PM me if you want to talk.
