How to build confidence around girls you like?

I am okay when i talk to girls i dont find attractive or iam not interested. But talking to attractive girls scares me a bit. I feel like if I approach a random girl it will be like i am bothering her or she will be like what this guy wants. Also i am not best at communication so i am scared it would be like me coming up to her and then dont know what to talk about.
