Look i've felt like that before, being shy but if I can give some advice. However you go about building more confidence or whatever you call it just a odd little hint. Unsure if you've ever ordered a Sub at Subway?
This is a great way to build confidence, every time you do it, you talk a bit back and forth with who is preparing your meal and you get some interaction with a new person every time, and it just helps you feel better. Later on you can make a compliment on how cool so and so is etc. I know this sounds so random to say, but just one little odd thing of so many things that randomly has helped me with shyness and anxiety over time .
